Question

A charge of `25 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `32 J` to `21 J`, what is the voltage between points A and B?

Answer 1

`v_(AB)=-11/25 V`

Explanation:

`Delta W=q(V_B-V_A)`
`Delta W=W_2-W_1=21-32=-11J`
`-11=25v_(AB)`
`v_(AB)=-11/25 V`
