How is it possible to have a high current with a low voltage such as in a car battery if current equals Voltage divided by Reistance then shouldn't a low voltage produce a low current?
It's all relative. A battery has internal resistance. Batteries are not "ideal" voltage sources. If there is a "heavy" load on the battery (low resistance), the voltage you measure on the outside of the battery will be lower. A car battery is normally thought of as a 12 volt battery. When there is no load (disconnected) you can often measure in excess of 13 volts if it's fully charged. During normal cranking of the engine, the voltage can drop below 11 volts.
Do cars use disposable batteries or rechargeable batteries?
The battery that starts the engine and runs all the electronics is a rechargeable battery. The only disposable battery may be the one in the remote for the car.
How does an alternator produce different amps?
It depends on the load and the voltage. In an automobile, a battery will typically have a voltage of about 12 Volts. If the engine is not running and you turn on the lights, the lights will start drawing current from the battery and the voltage will drop by a volt or so, depending on how strong a charge the battery has. An alternator will produce in the neighborhood of 15 Volts. If it is trying to push current into a system with a fully charged battery, it will only be able to push a few amps. If the voltage in the battery drops, the alternator will be able to push more amps. A completely dead battery will draw the most current (amps).
Example of primary battery?
Primary Batteries are non-rechargeable devices that are manufactured with a one-time charge built into them. Secondary batteries are rechargeable, and are manufactured with no inbuilt charge, so they must be charged before use. Note: Car batteries are nowadays built with coated plates so that they have an apparent charge when first installed. This is because cars do not have starter handles no, so installing an empty battery would present a problem in that the engine cannot be started to charge the battery.
How can we check the starter's external wiring circuit for volt drop?
For voltage drop checking on the wire from the battery positive post to the starter main terminal, you place the voltmeter reading on the 1 to 3 volt range, (or what lower range you have). You then place one voltmeter lead on the positive battery post, the other lead you place on the starter positive terminal and have someone crank the engine. While the engine is cranking, you observe the voltage drop. It should be less than a volt. This seems strange because you would think the cable would not drop voltage but it sure can. If the battery post is dirty or bad connection, you could see a voltage drop all the way to the maximum 12 volts battery voltage depending upon the connection. Also you can check the return path the same way--- Negative case of the starter to the negative post on the battery for voltage drop. If it is more than a volt or two, you have a bad ground return circuit.
Why wont the battery recharge on your 1980 suzuki gs 550 l?
Hi, Either bad charging system or battery. Check battery voltage itself and then voltage to battery with engine running. Healthy charging system will put out 1.5 to 2.0 volts above battery voltage. Motorcycles are notoriously rough on batteries. Peace, crigby
Do your check engine light stays on after you charge your battery?
i just changed my batterys out on my truck now my check engine light is on?
How do you jump start two 12 batteries?
To jump start an engine via the battery; the remote battery and the host battery, being of the same voltage, should be connected in parallel. That is positive terminal to positive terminal, negative to negative.
Can a car recharge its own battery if the battery goes completely dead?
A car cannot recharge its own battery if the battery is completely dead, because you need excitation voltage in the rotor to develop a voltage in the stator. Besides, you need voltage to run the ignition/computer system, and you need voltage to start the engine. That said, most batteries are not completely dead. If you can jump start the car, and assuming there is no electrical problem anywhere, you can run the engine and charge the battery. Problem is that most car batteries are not designed for deep discharge, and the probability that damage was done is greater than normal. Also, if the battery is very deeply discharged, you probably ought to charge it with an external charger (with the battery disconnected from the car) until its voltage is somewhat normal and its electrolyte is within limits for specific gravity.

How do you replace the voltage regulator on a 2000 Chrysler Town and Country?
The voltage regualtor is part of the engine computer. You will have to replace it. You will need to remove the battery to access.The voltage regualtor is part of the engine computer. You will have to replace it. You will need to remove the battery to access.

How far should the voltage on a car battery drop when cranking the car?
when cranking the engine the battery voltage should not fall below 9.6volts if so replace battery
What type of energy do the car and the batteries in the car have?
The Alternator outputs AC voltage which is converted to DC voltage. The battery stores DC voltage. The engine and all electronics run on 12 volts DC. The spark plugs fire with thousands of DC volts that are produced by the coils. It is all electrical energy.
How do you define voltage regulator?
A voltage regulator is a part of the engine that keeps the vehicle from sending too much electricity through the engine from the battery.
Where is the voltage regulator found on a 1994 Plymouth acclaim?
The engine computer, behind the battery, is the voltage regulator.
Why battery voltage reading decrease when you accelerate the engine?
Alternator is defective.
