The electric potential difference between the ground and a cloud


The electric potential difference between the ground and a cloud in a particular thunderstorm is 1.2 \times 10^{9} V. In the unit electron-volts, what is the magnitude of the change in the electric potential energy of an electron that moves between the ground and the cloud?

Solution:

The magnitude is \triangle U = e\triangle V = 1.2 \times 10^{9} eV = 1.2 GeV
