Question

A piece of wire of resistance Ris cut into five equal parts. These parts are then connected in parallel. If the equivalent resistance of this combination is R', then the
ratio R/R'is -
(a) 1/25
(b) 1/5
(c) 5
(d) 25​

Answer 1

d) 25 is the right answer

sorry previously I had given wrong answer

Answer 2

Answer: 25

Explanation:

Here is the explanation

If wire is cut into five parts

Therefore resistance of each part=R/5

1/reqR=1/r1|+1/r2+1/r3+1/r4+1/r5

1/ req R = I/R/5+1/R/5+1/R/5+1/R/5+1/R/5

1/req R=25/R

ReqR(R') =R/25

R/R'=R/R/25=25
