विकल्प
$$\mathrm{I} \times \mathrm{R} \times t$$
$$\mathrm{I} \times \mathrm{R}^{2} \times t$$
$$\mathrm{I}^{2} \times \mathrm{R} \times t$$
$$\frac{I^2 \times R}{t}$$

उत्तर
$$\mathrm{I}^{2} \times \mathrm{R} \times t$$
Explanation:
The electrical energy produced in a resistance is $$W = I^2Rt$$.
The other options either use incorrect powers of current or resistance, or divide by time instead of multiplying by it.
