A piece of wire of resistance R is cut into five parts of equal length – InterviewSolution

1.	A piece of wire of resistance R is cut into five parts of equal length. These parts are then connected in parallel. If the equivalent resistance of the parallel combination is R′, then the ratio RR′ is:
Answer» A piece of wire of resistance $R$ is cut into five parts of equal length. These parts are then connected in parallel. If the equivalent resistance of the parallel combination is $R^{^{'}}$ , then the ratio $\frac{R}{R^{^{'}}}$ is:
