Question:

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

(a) I2R               (b) IR2

(c) VI                (d) V2/R        [NCERT]

Answer:

(b) IR2

Explanation : Electric Power = VI

                                               = IR (R)

                                               = I2R

                                               =V [ V/R]

                                              = V2/R
