A piece of wire o

Answer :

The resistance of wire is R. This wire is cut into five equal pieces as a result resistance of each piece of wire will be R⁄5.Now, when these five pieces are connected in parallel, the equivalent resistance for the combination is R’. We can write,
(Assume that each piece of wire is named R1, R2, R3, R4, R5)

Thus, the correct answer is: Option (d)
