Physics PYQ 201 of 288 · Electricity

In which of the following ways can 1 volt be expressed?

  1. A1 Joule per Coulomb
  2. B1 Coulomb Joule
  3. C1 Joule-Coulomb
  4. D1 Joule-Coulomb second

BPSC CDPO Prelims 2005

Show answer and explanation

Correct answer: (a) 1 Joule per Coulomb

Explanation

Potential difference is the work done per unit charge: V = W/Q. So 1 volt = 1 joule per coulomb.
