## How are units of volts and electron volts related? How do they differ?

Volts (V) and electron volts (eV) are two different units used to measure electric potential or energy.

A volt (V) is the standard unit used to measure electric potential difference or voltage. It represents the amount of energy required to move one coulomb of charge through an electric potential difference of one volt.

An electron volt (eV), on the other hand, is a unit of energy used in atomic and subatomic physics. It represents the amount of energy gained by an electron when it is accelerated through an electric potential difference of one volt. One electron volt is equivalent to 1.6022 x 10^-19 joules.

In summary, volts measure electric potential difference, while electron volts measure energy. The difference between the two units lies in the amount of energy being measured, as electron volts are used to measure energy on a much smaller scale in the atomic and subatomic world.
