How much energy is needed to move one electron through a potential difference

of 1.0 x 10^{2} volts? Remember that the charge of an electron, e, is 1.6 x 10^{-19} C.

We will use the equation ΔV = (ΔU_{E}) /q. We plug in all of the given values and

we get 1.0 × 10^{2} = (ΔU_{E}) / (1.6 × 10^{-19}) , ΔU_{E} = 1.6 × 10^{-17} J
