What You Need to Know About Car Battery Voltage
Standard car batteries are listed as 12-volt batteries. However, this is rounding down, as a car battery should have a "resting voltage" – which is to say, the amount of voltage it has when it''s turned off – of 12.6 volts. That voltage increases when the car is running.

Bevan Paynter The QP 2261 measures voltage - not current. It assumes that for a given voltage drop of a battery during cranking, the battery must have delivered a corresponding current. It assumes that for a larger voltage drop, there must be a larger battery
Get PriceDo batteries lose voltage as they''re used up?
$begingroup$ Although I''m not sure that a single cell feeding a reasonable resistive load could deplete itself in a reasonable time to the point that its open-circuit voltage would fall to essentially nothing, it''s possible for some cells in a series-wired pack (which is all a "9-volt battery" is) to have their open-circuit voltage go negative. . Indeed, …

Get PriceHow do batteries work? A simple introduction
The higher the voltage, the more current a battery will produce when it''s connected into a given circuit, which is why this kind of voltage is sometimes called an electromotive force (EMF). The power something like a lamp or electric motor produces (or consumes) is proportional to the voltage across it, so a bigger voltage usually means …

When measuring the EMF of a battery and connecting the battery directly to a standard voltmeter, as shown in, the actual quantity measured is the terminal voltage V. Voltage is related to the EMF of the battery by V=emf−Ir, where I is the current that flows and r is the internal resistance of the battery.

Get PriceHow can there be a voltage when there is no current?
Large voltage at zero current! Blasphemy!!! So, if voltage isn''t caused by current, what then causes voltage? Simple: electric charge causes voltage, since electric charge is permanently associated with e-fields, and voltage is simply a description of e-fields. The misconception about current causing voltage seems to have a specific origin.
