A typical car battery has a voltage around 12V and a very small (less than 0.1 Ohm) internal resistance. If you would connect the ammeter in parallel to the battery it will hopefully trip the internal fuse or just blow up. There are very few specialized ammeters than can measure currents above 100A. So you have to approach this problem differently.
Drawing short-circuit current from a battery can damage or even explode the battery even if it is done for just a few seconds. The only way to know the current that a battery can handle safely is to find the …
The capacity of a battery is the amount of energy that the battery can store. This is usually measured in milliampere-hours (mAh) or ampere-hours (Ah). The higher the capacity, the longer the battery will last. Battery life is the amount of time that a battery can provide power before it needs to be replaced or recharged.

Describe how a galvanometer can be used as either a voltmeter or an ammeter. Find the resistance that must be placed in series with a galvanometer to allow it to be used as a voltmeter with a given reading. Explain why measuring the voltage or current in a circuit can never be exact. Voltmeters measure voltage, whereas ammeters measure current ...
An alternator that does not supply enough current at idle to keep up with the power demands can cause a battery to get drained. Then at high rpm, the alternator will provide maximum current it is capable of, and the battery will take all it can. Attaching circuits to the battery side of the ammeter.
