KVPY SA Exam 2012 Question Paper

In the circuit shown, n identical resistors R are connected in parallel (n > 1) and the combination is connected in series to another resistor ${\mathit{R}}_0$. In the adjoining circuit n resistors of resistance R are all connected in series along with ${\mathit{R}}_0$.The batteries in both circuits are identical and net power dissipated in the n resistors in both circuits is same. The ratio $\frac{{\mathit{R}}_0}{\mathit{R}}$ is
