Resistance `n`, each of `r ohm`, when connected in parallel give an equivalent resistance of `R ohm`. If these resistances were connected series, the combination would have a resistance in ohm, equal to

A

`R/n^2`

B

R/n

C

nR

D

`n^2R`

Text Solution

Verified by Experts

The correct Answer is:
D
According to question `R=r/n rArr r=nR`
`R_"series"=nr=n^2 R`
