Question

A charge of `6 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `33 J` to `12 J`, what is the voltage between points A and B?

Answer 1

`V_"AB"=-3,50" " V`

Explanation:

`Delta W=W_2-W_1=12-33=-21 J`

`V_"AB"=V_B-V_A`

`Delta W=q*V_"AB"`

`-21=6*V_"AB"`

`V_"AB"=-21/6`

`V_"AB"=-3,50" " V`
