The power consumed when \(10 \mathrm{~V}\) voltage is applied to a series combination of 10 resistors of each \(1 \Omega\) is \(\mathrm{P}_{\mathrm{s}}\) and the power consumed when the same \(10 \mathrm{~V}\) is applied to the parallel combination of these 10 resistors is \(P_p\). The value of \(\frac{\mathrm{P}_{\mathrm{s}}}{\mathrm{P}_{\mathrm{p}}}\) is
- A \(10\)
- B \(100\)
- C \(0.1\)
- D \(0.01\)
Answer & Solution
Correct Answer
(D) \(0.01\)
Step-by-step Solution
Detailed explanation
We have \(\mathrm{P}_{\mathrm{S}}=\frac{\mathrm{V}^2}{\mathrm{R}_{\mathrm{S}}}=\frac{10^2}{10}=10\) and, \(\mathrm{P}_{\mathrm{P}}=\frac{\mathrm{V}^2}{\mathrm{R}_{\mathrm{P}}}=\frac{10^2}{\frac{1}{10}}=1000\) So,…
