What is the minimum resistance which can be made using five resistors each of `(1//5) Omega` ?

A

`1//5 Omega`

B

`1//25 Omega`

C

`1//10 Omega`

D

`25 Omega`

Text Solution

Verified by Experts

The correct Answer is:
B

The minimum resistance is obtained when resistors are connected in parallel combination. Thus, equivalent resistance,
`R_(P) = (R)/(n) = (1//5)/(5) = (1)/(25) Omega, R_(p)` = equivalent resistance for parallel combination.
