Find the value of `R` for which no current will flow through `5V` battery

A

`4 Omega`

B

`1 Omega`

C

`3 Omega`

D

`4 Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) If no current flows through `5 V` battery, then potential difference across `f` and `e` is `5 V`. So potential diffenence across `d` and `c` is also `5 V`
`i= (10)/(R + 1)`
`iR = 5 implies (10)/((R + 1)) R = 5 implies R = 1 Omega`
