The difference in electric potential between a thunder cloud and the ground is 1.53 108 V. Electrons move from the ground which is at a lower potential to the cloud which is at a higher potential. Determine the change in electric potential energy of one of the electrons that move to the cloud.

=-2.451 330 152 1*10^27J

Explanation:

The electric potential=the Voltage * Charge:

E = VQ

V = 1.53x10^8 V (positive, because the cloud has a higher potential)

Q = - 1.60217657 x10^19 C (the charge of an electron)

E = (1.53x10^8 V) * (-1.60217657 x10^19 C)

E=-2.451 330 152 1*10^27J

The negative sign indicates that the potential energy is decreased by the movement of the electron.
