MCQ
Electron volt is a unit of
  • A
    Potential
  • B
    Charge
  • C
    Power
  • ✓
    Energy
✓

Answer

Correct option: D.
Energy
d
(d) The electron volt (symbol $ev$ also written electronvolt) is a unit of energy equal to approximately $1.602 \times 10 ^{-19}$  joule $(SI$ unit $J).$

By definition, it is the amount of energy gained by the charge of a single electron moved across an electric potential difference of one volt.
