# Definition of electron volt or EV The concept of Electron volt is very simple. Let’s start with very simple. We know that the unit of power is the watt. W = VI, where V is the voltage and I is the current.

Now that I’m up to date, it’s nothing but a fee transfer. Therefore, an immediate impression of power would be

Where q (t) is the amount of charge transferred in time t. Now energy is being expressed in

Where q is the charge in Coulomb crossing a voltage V volts. From the expression of energy, we can write the required energy or work

to cross an electric field of total voltage V through a load Q Coulomb, QV Coulomb – Volts, or Joules.

We now know that the charge of an electron is 1.6 × 10-19 Coulomb,

and assume that it has undergone an electric field with a total voltage of 1 V electron × 1 V.

This amount of energy is called the micro-unit of energy, which is called the electron volt.

## Definition of an electron volt

An electron volt is the energy unit in joules that corresponds to the

amount of work required to bring an electron into a 1-volt electrical difference field.

It is a very small or small energy unit that is mainly used for various

calculations at the atomic and electronic level.

The concept of energy levels in materials is treated in this micro-unit of electron-volts energy.

This device not only uses the energy of the electrons but also all kinds

of energy like heat energy, light, etc.
