Three resistances, each of 1 ohm , are joined in parallel. Three such combinations are put in series, then the resultant resistance will be

A

`9Omega`

B

`1Omega`

C

`3Omega`

D

`1/3Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
For each row of three resistance In parallel,
`R=1/3Omega`
For three such rows In series,
`R_"eq"=1/3xx3=3/3`
`=1Omega`
