Three resistance, each of `1Omega`, are joined in parallel. Three such combinations are put in series. The resultant resistance is

A

`9Omega`

B

`3Omega`

C

`1Omega`

D

`(1)/(3)Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
`R_(p)=1+1+1=3Omega, (1)/(R_(S))=(1)/(3)+(1)/(3)+(1)/(3)=(3)/(3)=1 rArr R_(S)=1Omega`
