Question

A charge of `15 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `24 J` to `12 J`, what is the voltage between points A and B?

Answer 1

`V_(B)=-4/5 V`

Explanation:

`"Work doing by Electrical Forces is defined as:"`
`Delta W=q(V_B-V_A)`
`12-24=15(V_B-V_A)`
`V_B-V_A=V_(AB)`
`-12=15*V_(AB)`
`V_(AB)=-12/15`
`V_(B)=-4/5 V`
