Do not understand your notation.
Do you mean
2.13 * 10^8 Volts ????
anyway
energy in Joules = potential in Volts * charge in Coulombs
The potential difference between a storm
cloud and the ground is 2.13 × 108 V.
If a bolt carrying 2 C falls from a cloud to Earth, what is the magnitude of the change of potential energy of the charge?
