Question

A piece of wire having a resistance of 5 ohm cut into five equal parts. If the five parts ofthe wire are connected in parallel, then find the effective resistance of the combination?​

Answer 1

Answer:

Consider the wire of resistance 'R' is cut into five equal parts.  

Thus, Resistance of each part will be R/5.

Equivalent resistance R' will be given by,

1/R' = 5/R + 5/R + 5/R + 5/R + 5/R  ...( resistances connected in parallel)

Thus, equivalent resistance R'=R/25

Answer 2

Answer:

if the five equal pieces of a resistance wire having 5 ohm resistance each is connected in parallel, then their equivalent resistance will be? Answer: ... Thus, Resistance of each part will be R/5.
