How does a phase leg connect to a neutral in an electrical circuit?
A phase leg connects to the neutral through the connected load.
What will happen if a phase and neutral test by a mutimeter shows continuity?
If the test shows that there is a continuity between the phase leg and the neutral with no load connected, then that circuit should not be energized. If the circuit was energized then the fuse or breaker protecting that leg will trip the circuit open.
What is 7815 voltage regulator?
A LM7815 voltage regulator is a component designed to maintain a constant voltage level, the LM78XX series of voltage regulators are designed for positive inputs and has the ability to drive the current within the circuit up to 1A. The component has three legs: Input leg which can hold up to 36VDC, a leg that leads straight to ground and an output leg with the regulated voltage. For maximum voltage regulation, adding a capacitor in parallel between the ground leg and the output leg will improve efficiency.
When resistors are connected in series in a circuit. what are the relationships between the voltage drops across the resistor and the currents through the resistors?
When resistors are connected in series in a circuit . the voltage drop across each resistor will be equal to its resistance, as V=IR, V is direct proportional to R. An A: The relationship is that the current will divide for each paths in a parallel circuit and the voltage drop across each will be the source voltage. In a series circuit the current will remain the same for each component but the voltage will divide to reflect each different component value. And the sum of all of the voltage drops will add to the voltage source
How should a fuse or circuit breaker be used?
Yes there should be an in-line fuse. If there is not an in-line fuse and there is a voltage spike in the vehicle the fuse will pop and disable the circuit where as if there was no fuse the accessory or mechanism could be destroyed. As above suggests, the fuse must be put in series. If it is in parallel, the fuse should blow immediately on completing the circuit, because it is effectively a short, which will cause large current flow into the fuse until it blows. Never, never, never put a fuse in parallel with whatever you want to protect - that defeats the point of the fuse.
In a parallel circuit a parallel branch is uaually called a what?
It's usually referred to as one leg of the circuit.
What is the difference between parelllel and series circuit?
A parallel circuit has the same voltage but different current in each leg and series circuit has the same current but different voltage on each components unless the same value.
What is the difference in a parallel circuit and a series circuit?
In a parallel circuit, the components are connected to the same voltage source but have their own separate branches, offering multiple paths for current to flow. In a series circuit, the components are connected in a single path, and the same current flows through each component sequentially.
Can there be a different voltage across each component in a circuit?
Yes, if it is a series circuit. In an ideal parallel circuit, there is equal voltage in each leg. In a real circuit, results may vary if there is voltage loss in the wiring.
Is the current always the same in parallel circuits?
An example of a parallel circuit would be the light bulbs in track lighting. Each bulb has the same voltage applied. The current through any one light bulb equals the voltage divided by the resistance of the bulb. The current also equals the wattage of the bulb divided by the voltage. So if all the bulbs had exactly the same resistance the current would be the same. However, your question says "always" so in general the answer is no. In the case of track lighting if you had a 60 watt bulb in parallel with a 120 watt bulb, the 60W bulb would draw 1/2 amp and the 120W bulb would draw 1 amp. The sum of the current flowing in a parallel circuit equals the sum of the current in each leg of the circuit.
Is a branch voltage in each branch of a parallel circuit less than the applied voltage?
Yes. In a 240 volt circuit, the total applied voltage is 240 volts but each leg is carrying only 120 volts.
Why does parallel circuit have higher current than the series?
Parallel branches each draw a current from the supply. The more branches, the more current is drawn. Adding additional loads to a series circuit increases its resistance, causing its supply current to reduce.
What does the common leg of a 110 circuit do?
Nothing
If an electric current is flowing through a parallel circuit which units tell you about the amount of electrons traveling in the circuit?
It makes no difference whether the circuit is parallel, series or complex. The number of electrons travelling (or oscillating back and forth for AC) is determined by the current (amps). 1 amp = 1 coulomb/second. 1 coulomb = the charge represented by 6.24150962915265 x 1018 electrons. The current in each leg of a parallel circuit has to be worked out separately.
How many soccer players have a leg injury?
EVERY soccer player because we are all the same from the inside #ILOVESOCCER
How does a phase leg connect to a neutral in an electrical circuit?
A phase leg connects to the neutral through the connected load.
What will happen if a phase and neutral test by a mutimeter shows continuity?
If the test shows that there is a continuity between the phase leg and the neutral with no load connected, then that circuit should not be energized. If the circuit was energized then the fuse or breaker protecting that leg will trip the circuit open.
