Connect your positive current running from your cars battery to the plus sign on the cap and the ground from your car to the negative ( note.. Cap must be charged befor installing read manuals to charge ) not cut two wires one for positive current and one for ground those wire are going to run from your cap to your amp....there you go now your battery and alternator will be given a break
Yes you can. Its best to keep the amps within 18 inches or 1.5 feet of the cap. All a cap does is supply the power the battery can't deliver at that given moment. Make sure to separate each ground on both amps and the cap.
**** caution**** very much danger......on the cap there should be 2 terminals....+ and a - .....first thing is to undo the power supply the cap goins inline on the (+) side of the power supply and also hook the (-) to the ground inlined with the amp......do NOT EVER EVER EVER TOUCH OR ARC ACROSS THE CAPS TERMINALS....THIS CAN BURN UP THE CARS ELECTICAL SYSTEM AND OR KILL YOU BY STOPPING YOUR HEART.......SO HOOK THE CAP IN BEFORE YOU HOOK UP THE (+) POWER TO THE SYSTEM
A capacitor of 0.5 Farad should have screw or spade terminals, with clear polarity markings. POLARITY IS EXTREMELY IMPORTANT! The "-"/negative terminal needs to be connected to ground, while the +/positive is connected to the vehicle power. Reversing polarity will cause the capacitor to explode. You will also want to charge the capacitor initially through a resistor to prevent blowing a fuse/breaker. A 100 ohm resistor will keep the current below roughly 100mA during charging. Let capacitor charge 15-20 minutes if it is a fully discharged capacitor. Once charged remove resistor and connect power cable directly to capacitor. Once charged, large capacitors can dump large amounts of current, creating a fire hazard! Ensure all connections are well insulated once connected, and the power cable is sized to match the power of the component.
Answer The easiest way is to connect it directly to the battery. Make sure the polarity matches up. (-ve to -ve, and +ve to +ve). Because it is 1F, it will take some time to charge. (probably a minute or two.) In that way, the capacitor will charge to whatever the voltage of the battery. But won't be fully charged,
In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. Inside the battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal. A capacitor is much simpler than a battery, as it can't produce new electrons -- it only stores them. Inside the capacitor, the terminals connect to two metal plates separated by a non-conducting substance, or dielectric. You can easily make a capacitor from two pieces of aluminum foil and a piece of paper. It won't be a particularly good capacitor in terms of its storage capacity, but it will work. In theory, the dielectric can be any non-conductive substance. However, for practical applications, specific materials are used that best suit the capacitor's function. Mica, ceramic, cellulose, porcelain, Mylar, Teflon and even air are some of the non-conductive materials used. The dielectric dictates what kind of capacitor it is and for what it is best suited. Depending on the size and type of dielectric, some capacitors are better for high frequency uses, while some are better for high voltage applications. Capacitors can be manufactured to serve any purpose, from the smallest plastic capacitor in your calculator, to an ultra capacitor that can power a commuter bus. NASA uses glass capacitors to help wake up the space shuttle's circuitry and help deploy space probes. Here are some of the various types of capacitors and how they are used. Air - Often used in radio tuning circuits Mylar - Most commonly used for timer circuits like clocks, alarms and counters Glass - Good for high voltage applications Ceramic - Used for high frequency purposes like antennas, X-ray and MRI machines Super capacitor - Powers electric and hybrid cars Capacitor Circuit In an electronic circuit, a capacitor is shown like this: When you connect a capacitor to a battery, here's what happens: • The plate on the capacitor that attaches to the negative terminal of the battery accepts electrons that the battery is producing. • The plate on the capacitor that attaches to the positive terminal of the battery loses electrons to the battery. Once it's charged, the capacitor has the same voltage as the battery (1.5 volts on the battery means 1.5 volts on the capacitor). For a small capacitor, the capacity is small. But large capacitors can hold quite a bit of charge. You can find capacitors as big as soda cans that hold enough charge to light a flashlight bulb for a minute or more. Even nature shows the capacitor at work in the form of lightning. One plate is the cloud, the other plate is the ground and the lightning is the charge releasing between these two "plates." Obviously, in a capacitor that large, you can hold a huge amount of charge! Let's say you hook up a capacitor like this:Here you have a battery, a light bulb and a capacitor. If the capacitor is pretty big, what you will notice is that, when you connect the battery, the light bulb will light up as current flows from the battery to the capacitor to charge it up. The bulb will get progressively dimmer and finally go out once the capacitor reaches its capacity. If you then remove the battery and replace it with a wire, current will flow from one plate of the capacitor to the other. The bulb will light initially and then dim as the capacitor discharges, until it is completely out. Farad A capacitor's storage potential, or capacitance, is measured in units called farads. A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amprepresents a rate of electron flow of 1 coulomb of electrons per second, so a 1-farad capacitor can hold 1 amp-second of electrons at 1 volt. A 1-farad capacitor would typically be pretty big. It might be as big as a can of tuna or a 1-liter soda bottle, depending on the voltage it can handle. For this reason, capacitors are typically measured in microfarads (millionths of a farad). To get some perspective on how big a farad is, think about this: • A standard alkaline AA battery holds about 2.8 amp-hours. • That means that a AA battery can produce 2.8 amps for an hour at 1.5 volts (about 4.2 watt-hours -- a AA battery can light a 4-watt bulb for a little more than an hour). • Let's call it 1 volt to make the math easier. To store one AA battery's energy in a capacitor, you would need 3,600 * 2.8 = 10,080 farads to hold it, because an amp-hour is 3,600 amp-seconds. If it takes something the size of a can of tuna to hold a farad, then 10,080 farads is going to take up a LOT more space than a single AA battery! Obviously, it's impractical to use capacitors to store any significant amount of power unless you do it at a high voltage. Applications The difference between a capacitor and a battery is that a capacitor can dump its entire charge in a tiny fraction of a second, where a battery would take minutes to completely discharge. That's why the electronic flash on a camera uses a capacitor -- the battery charges up the flash's capacitor over several seconds, and then the capacitor dumps the full charge into the flash tube almost instantly. This can make a large, charged capacitor extremely dangerous -- flash units and TVs have warnings about opening them up for this reason. They contain big capacitors that can, potentially, kill you with the charge they contain. Capacitors are used in several different ways in electronic circuits: • Sometimes, capacitors are used to store charge for high-speed use. That's what a flash does. Big lasersuse this technique as well to get very bright, instantaneous flashes. • Capacitors can also eliminate ripples. If a line carrying DC voltage has ripples or spikes in it, a big capacitor can even out the voltage by absorbing the peaks and filling in the valleys. • A capacitor can block DC voltage. If you hook a small capacitor to a battery, then no current will flow between the poles of the battery once the capacitor charges. However, any alternating current (AC) signal flows through a capacitor unimpeded. That's because the capacitor will charge and discharge as the alternating current fluctuates, making it appear that the alternating current is flowing.
No. The capacitor is there to store the power so that the power isnt drained from the car at once. It helps reduce the strain placed on the vehicles electric system.
assuming you have an amp. run the hotwire from your battery directly to the POSOTIVE terminal of the cap. the run another wire from the POSOTIVE cap terminal to the amps power input( where the wire went before) and the run a third wire from the caps NEGATIVE terminal to the car body(as a ground) i have one in my car it wrks good for about 500 watts after that u need stronger cap. good luck
The farad (symbol: F) is the SI unit of capacitance. It is named after Michael Faraday. Definition A capacitor has a value of one farad when one coulomb of stored charge causes a potential difference of one volt across its terminals. Explanation Since the farad is a very large unit, values of capacitors are usually in range of microfarads (μF), nanofarads (nF), or picofarads (pF). The picofarad is comically called a "puff" in laboratory usage. The millifarad is rarely used in practice, so that a capacitance of 4.7�10−3 F, for example, is usually written as 4700 μF. Very small capacitance values, such as those used in integrated circuits may also be expressed in femtofarads, one femtofarad being equal to 1�10−15 F. A new technology called supercapacitors offers devices up to the kilofarad range. The farad should not be confused with the faraday, an old unit of charge nowadays superseded by the coulomb. The reciprocal of capacitance is called electrical elastance, the (non-standard, non-SI) unit of which is the daraf. A capacitor consists of two conducting surfaces, often referred to as plates, separated by an insulating layer usually referred to as a dielectric. The original capacitor was the Leyden Jar developed in the 18th century. It is the accumulation of charge on the plates that results in capacitance. Modern capacitors are constructed using a range or manufacturing techniques and materials to provide the extraordinary wide range of capacitance values used in practical electronics applications from femtofarads to farads and voltage withstand capabilities from a few volts to a several kV.
I am going to assume that the capacitor in question has one uf or mfd rating and the one you want to use has two such as: 30+7.5uf if so then yet as long as you hook to the terminals that supply the same uf as the oem capacitor. The terminal marked HERM will be the terminal that has the highest of the two uf ratings. hope this helps!!
First, before installing the capacitor, you will need to *safely* charge it. Go to radio shack and get a 1K ohm resistor, 1/4 W size. Connect one lead of the resistor to the positive terminal of the capacitor. Then connect the negative terminal of the capacitor to ground. Use the same size cable as the amplifiers ground cable. You don't state how big these amps are, but you should be using something like 8 gauge or 4 gauge cable. If you are using anything smaller than that you need to rewire the system with the proper size cable. If you are not sure what size you need, email me at nfhiggs@pacbell.net with your complete audio system specs and I'll calculate it for you. Next connect the other lead of the resistor to the positive cable from the battery. I'm assuming you are using a 1 Farad capacitor here so the charging will take some time maybe a half hour to an hour or more (the time constant for a 1 farad cap and a 1K resistor is 1000 seconds and it takes five time constants to fully charge a capacitor), but this is not something you want to rush, because if you don't use a resistor to charge it, you could do serious damage to your wiring or possibly blow up the cap. Monitor the charge on the capacitor with a multimeter, and when it gets to 12V, remove the resistor. To connect it to your system, simply connect the positive cable coming from the second battery to the positive terminal of the cap (the ground is already connected), then run cables from the capacitors positive terminal to the Amplifiers' main power input terminals.
The general rule for adding vectors is to hook them together "head to tail" and then draw in a resultant vector. The resultant will have the magnitude and direction that represents the sum of the two vectors that were added.
The capacitor charges up when you initially install it and apply 12 volts to the circuit. Its purpose is to smooth out power drops in the 12 volt supply line to the amp. For instance, when the bass hits the speakers, the amperage surge can exceed the amperage the line delivers for a split second, so the capacitor supplies amperage briefly to sustain the power. Hooking up a small motorcycle battery close to the amp serves the same purpose but is possibly messier because of the potential to leak acid.
