Question

A charge of `8 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `64 J` to `8 J`, what is the voltage between points A and B?

Answer 1

Electric potential is `("Energy")/("Charge")`, and the potential difference is the change in potential.

Explanation:

`V=E/Q`
`Delta V=(Delta E)/Q`
`Delta V=(8J-64J)/(8C)`
`Delta V=-7 V`

There is a 7V drop from A to B,
