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»

Correct option(d)

Explanation:

Resistance of wire = R 

If the wire is cut into n equal parts, the resistance of each wire is R/n and connected in parallel. 

Req = R/n2
