Q.

A wire of resistance R is cut into ‘n’ equal parts. These parts are then connected in parallel. The equivalent resistance of the combination will be –

A. nR
B. R/n
C. n/R
D. R/n²
Answer» D. R/n²
Explanation: Since R is directly proportional to length of the wire, when wire is cut into equal parts, then Resistance of each part = R/n
