Outside the battery:The path for conventional current goes from the positive terminal (+, usually a red wire) to the negative terminal (−, usually a black wire).A wire's electrons flow from the negative (−) terminal to the positive (+) terminal.Since the current forms a continuous a loop in the same direction, the direction inside the battery is "backwards".Inside the battery:Conventional current flows from the negative (−) terminal to the positive (+) terminal.Positive ions flow from the negative (−) terminal to the positive (+) terminal.Negative ions flow from the positive(+) terminal to the negative (−) terminalConventional current assumes that all flowing charges are positive. It simplifies the situation because it hides the more complicated electrons, positive ions, and negative ions.
protons-positive neutrons-neutral electrons-negative
It is very common for the battery to discharge on a vehicle sitting idle for 3 months. First disconnect the positive + & negative- battery cables, and clean the battery post and cable connections off. Apply a thin layer of dielectric grease or Vaseline to the battery post and connect the negative - cable. Put a battery charger on the battery and let it fully charge overnight. If it will not accept a charge it is defective. It it does show fully charged, connect the positive + cable and see if the engine will start. if not, then more than likely the battery is dead and needs replacing.
This could be the voltage regulator. Both the positive from the battery and the starter would be connected to it.
A proton has a positive charge which is equal in magnitude but opposite to the charge on an electron, which is negative.
Recharge: By having a positive charge applied to the positive contact of the battery, and by having a negative charge applied to the negative contact of the battery. Discharge: complete a circuit between both contacts of the battery.
An alternator has diodes which transform ac voltage to dc voltage so that the battery gets negative and positive current on its poles thus making the battery to be charged.
Connect the positive clip of the battery charger to the positive terminal on the battery. Connect the negative clip of the battery charger to the negative terminal on the battery. Select the charge rate you desire either 2,4, or 6 amp. The newer battery chargers will let you know when it is fully charged.
The electron is a negative charged particle.The positron is a positive charged particle.
Assuming neither battery is used to start the engine, simply connect the positive (+) terminal of the first battery to the positive terminal of the second battery. Then connect the negative (-) terminal of the first battery to the negative terminal of the second battery. Connect the load circuit to the positive and negative terminals of one of the batteries as usual. You may want to charge the batteries separately before making the connection, since connecting a charged battery to a discharged battery will result in a very large current flowing from the charged battery to the discharged battery, possibly damaging the wiring or either battery.
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
The short answer is that they don't. But that doesn't help you much. Electrons flow from the negative terminal to the positive terminal. Why? Negative and positive (opposite) charges attract each other, and like charges repel each other. So you can think of the positive charged end pulling electrons towards it, as well as the negative charged end pushing electrons away from it. Water makes a good analogy, the battery is a pump, so there is high pressure on the outlet of the pump ( the negative terminal ) through the pipes and whatnot, ( the wire and whatnot) to the inlet of the pump ( the positive charged end ).
Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive.
because batteries works on the principle of electron charge and an electron can have either a more positive or negative charge but the electron wants to have an equal amount of pos. and neg. charge so when batteries are simply they pull the positive charge to one side and negative to the other side and when they come together with a conductor(wire) it creates a current which does the "work" for you. The voltage of the battery pretty much lets you know how strongly the battery wants to create equality between each side thus more current.
Take a DC volt meter and check the voltage at the battery. Red probe on positive + terminal and Black probe on negative - terminal. If it reads 12.6 volts it is fully charged. 12.4 and it is 75%, 12.2 and it is 50%, 12.0 and it is 25% charged. Less than 12 volts and it is considered a dead battery.
Nitrogen is negatively charged.
Electrons are negatively charged.
