Question

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

Accepted Answer

For parallel combination, power $P = \frac{V^2}{R}$. Therefore, $\frac{P_1}{P_2} = \frac{R_2}{R_1} = \frac{200}{100} = \frac{2}{1}$.
