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

A

`I^2R`

B

`IR^2`

C

` VI`

D

`V^2/R`

Text Solution

Verified by Experts

The correct Answer is:
B
Electric power P = VI = (IR) I = `P^2R`
`=(V/R)^2 R = V^2/R`.
Thus, the three expressions given in (a), (c) and (d) represent power while expression given in (b) does not.
