Question

During a particular thunderstorm, the electric potential between a cloud and the ground is vcloud - vground = 1.5 x 108 v, with the cloud being at the higher potential. what is the change in an electron's potential energy when the electron moves from the ground to the cloud?

Answer 1

Voltage is potential energy per coulomb (J/C). So use the voltage and charge on an electron to get E=V•Q=1.5e8•1.602e-19=2.4e-11J
