Which of the following terms does NOT represent electric power in a circuit?

Explanation

Among the given options, IR² does not represent electric power in a circuit. Electric power is the rate of conversion of electrical energy. It is defined as the rate of transfer of energy in an electric circuit, or the rate of doing work in an electric circuit. Electric power can be represented by P. The SI unit of electric power is watt. Mathematically, electric power is expressed as the product of potential difference and current in a circuit: $$P = V \times I$$ $$P = V \times \frac{V}{R} = \frac{V^2}{R}$$ or, $$P = IR \times I \left[ \because I = \frac{V}{R} \right]$$ $$= I^2R \left( \because V = IR \right)$$ (367) ## Page 16
