If a charge q = 2 C moves through a potential difference ΔV = 12 V, what is the change in electric potential energy ΔU?

Explanation:
Electric potential energy changes when a charge moves through a potential difference according to ΔU = q ΔV. Here the charge is positive, so the potential energy increases by that amount. Compute ΔU = (2 C)(12 V) = 24 J. The unit check works since volt times coulomb equals joule. If the charge or the potential difference were reversed in sign, the result would change sign accordingly.
