Question

a wire of resistance R cut into 5 equal pieces This pieces ae connected in parallel and equivalent resistance of the combination R/R' then what is the ratio of it​

Answer 1

Answer:

25

Explanation:

As R is cut into 5, resistance of each piece= R/5

1/R' = 5(5/R) As in parallel circuit 1/R = 1/R+1/r

R' = R/25.

R/ R' = R/R/25

= 25
