Solution

Electron volt:

  1. 1eV is defined as the energy gained by an electron when it has been accelerated by a potential difference of 1volt, hence 1eV=1.60210-19J.
  2. eV stands for electron volt.

Mathematically,

W=qV=1e-C(1V)JCW1eV=1.6×10-19J

Here,

eV is the electron volt.

J is the joules.

W is the work done.

q is the charge.

V is the potential difference.

Therefore, it is the energy an electron would gain in moving between two points having a potential difference of 1volt.
