Question:medium
Two heaters rated as \((P_1,V)\) and \((P_2,V)\) are connected in series across a dc source of \(V/2\) volt. The power consumed by the combination will be –
Two heaters rated as \((P_1,V)\) and \((P_2,V)\) are connected in series across a dc source of \(V/2\) volt. The power consumed by the combination will be –
Show Hint
For appliances with rating \((P,V)\),
\[
R=\frac{V^2}{P}.
\]
Always convert the ratings into resistance first and then apply series or parallel combinations.

- \((P_1+P_2)\)
- \(\dfrac{P_1+P_2}{2}\)
- \(\dfrac{P_1P_2}{2(P_1+P_2)}\)
- \(\dfrac{P_1P_2}{4(P_1+P_2)}\)
Show Solution
The Correct Option is D
