Question 192: Current Electricity

Question

Ratio of thermal energy released in two resistors R and 3R connected in parallel in an electric circuit is :

Accepted Answer

For parallel connection, potential difference is same $(v)$
$$
\begin{aligned}
& P_{1}=\left(\frac{v^{2}}{R_{1}}ight) \\
& P_{2}=\left(\frac{v^{2}}{R_{2}}ight) \\
& \frac{P_{1}}{P_{2}}=\frac{H_{1}}{H_{2}}=\left(\frac{R_{2}}{R_{1}}ight)=\frac{3 R}{R}=(3: 1)
\end{aligned}
$$
