Correct Answer - Option 2 : I R2

CONCEPT:

  • Electric Power: The rate at which electrical energy is dissipated into other forms of energy is called electrical power i.e.,

\(P = \frac{W}{t} = VI = {I^2}R = \frac{{{V^2}}}{R}\)

Where V = Potential difference, R = Resistance and I = current.

EXPLANATION:

  • From the above, it is clear that the formulas do not represent electrical power is IR2.
