Which of the following terms does not represent electrical power in a circuit :

Options

A. `I^2 R`
B. `I R^2`
C. `VI`
D. `V^2//R`

Answer

D

Explanation

Electric power, `P = VI = (IR) R = I^2 R`
=`V((V)/( R)) = (V^2)/( R)`
Obviously, `IR^2` does not represent electrical power in a circuit.
Thus, (b) is the correct answer.
