Electrical Power & Heating Effect

Two resistors of resistance, 100 $\Omega$ and 200 $\Omega$ are connected in parallel in an electrical circuit. The ratio of the thermal energy developed in 100 $\Omega$ to that in 200 $\Omega$ in a given time is

Show answer and solution

Answer: (b)

In parallel, $V$ is the same, so $H = \frac{V^2 t}{R} \propto \frac{1}{R}$ .
$\frac{H_{100}}{H_{200}} = \frac{200}{100} = 2 : 1$ .
So the answer is (b) 2 : 1.
