Question

A wire of resistance R is cut into 8 equal pieces. From these pieces two equivalent resistances are made by adding four of these together in parallel. Then these two sets are added in series. The net effective resistance of the combination is :NEET 2025

Options:

Answer:

C

Solution:

$Resistance of each part = R /8 R_{eq} = \frac{1}{4} (R /8) + \frac{1}{4} (R /8) = \frac{R}{16}$
