Three resistances, each of`1 Omega` are joined in parallel. Three such combinations are put in series. The equivalent resistance is given by

A

`9 Omega`

B

`1 Omega`

C

`3 Omega`

D

`(1)/(3) Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
For each row of three resistances in parallel,
`R=(1)/(3) Omega`
For three such rows in series
`R_(eq)=(1)/(3)xx3=(3)/(3)`
`=1Omega`
