During a particular thunderstorm, the electric potential difference between a cloud and the ground is Vcloud - Vground = 4.3 108 V, with the cloud being at the higher potential. What is the change in an electron's electric potential energy when the electron moves from the ground to the cloud?

Answer 1

Multiply the potential difference (in volts) by the electron charge (in Coulombs). The answer will be in Joules.

Put a minus sign in front of it since the potential energy of the electron drops when it moves to higher positive potential.
