Question

A charge of `9 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `27 J` to `12 J`, what is the voltage between points A and B?

Answer 1

-1.56volt

Explanation:

we know,
`V=(W_B-W_A)/q`
here,
`W_B=12j`
`W_A=27j`
`q=9C`
then, by putting the values in the equation,
`V=(12j-27j)/(9C)`
`=(-14j)/(9C)`
`=-1.56jC^(-1)`
`=-1.56vol t`
