# The voltage of a battery is the?

The voltage of a battery is the

Question 17 options:

Amount of charge produced by the battery

Energy supplied per coulomb of charge or work done per unit charge for the output by the battery

Amount of internal resistance of the battery

The power produced by the battery

Update:

I believe this is the answer: Energy supplied per coulomb of charge or work done per unit charge for the output by the battery

Energy supplied per coulomb of charge or work done per unit charge for the output by the battery ;

Q*V = A*sec*V = V*A*sec = work

V = work/coulomb (work per unit charge)

the second option is correct, qV = W, so V = W/q, or work per unit charge

None of these are really right. Voltage is a difference potential between the battery's terminals. It's electrical 'pressure'. None of these are here.

So I'll eliminate the worst answers and pick the least wrong one.

The power produced by the battery is watt-hours, not voltage.

The internal resistance reduces current flow but is not related to the battery's voltage.

Work done is a measure of power, i.e. watts or watt-hours. So no.

The amount of charge in a battery is measured as voltage, but that's an indirect measurement. It's like saying the magnitude of a flood is measured by how many people's feet got wet. We measure a battery's amount of charge by voltage, but that's not at all what voltage is! But this is the closest to being true so I'd go with this one.
