The Total resistance when connected in series in `9 Omega` and when connected in parallel is `2 Omega` The value of two resistance are

A

`2Omega` and `9Omega`

B

`3Omega` and `6Omega`

C

`3Omega` and `9Omega`

D

`2Omega` and `6Omega`

Text Solution

Verified by Experts

The correct Answer is:
B

Take the product of `R_(S)` and `R_(P)`. Find out factors of product and select the pair of factors so that there addition should be equal to `R_(S)`.
i.e. `R_(S)R_(P)=9xx2=18`
`= 6xx3`
`:.R_(1)= 6 Omega` and `R_(2)=3 Omega`
