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

Options

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

Answer

B

Explanation

P = VI ... (i) So, the option (c) is correct. According to Ohm.s law, V = IR ... (ii) Now putting the value of V from (ii) in (i), we get Power P = (IR) x I = `I^(2)` R So, the option (a) is correct. Now putting the value of I from (ii) in (i), we get Power P = V(V`//`R) = `V^(2)//R` so, option (d) is correct
