Answer 1

Answer:

First of all your question is incomplete :-(

But fortunately I got your answer :-)

follow the steps given below.

Explanation:

R1= R/5

R2= R/5

R3= R/5

R4= R/5

R5= R/5

1/R'= 1/R/5 + 1/R/5 + 1/R/5 + 1/R/5 + 1/R/5

1/R'= 5/R + 5/R + 5/R + 5/R + 5/R

1/R'= 25/R

R'= R/25

R/R'= R/R/25

R/R' = R x 25/R    [We will cancel the R]

R'=25
