In the circuit shown, a meter bridge is in its balanced state. The meter bridge wire has a resistance `.1 ohm//cm`. The value of unknown resistance `X` and the current drawn from the battery of negligible resistance is

A

`6 Omega, 5 amp`

B

`10 Omega, 0.1 amp`

C

`4 Omega, 1.0 amp`

D

`12 Omega, 0.5 amp`

Text Solution

Verified by Experts

The correct Answer is:
C
`(X)/(6) = (40)/(60) rArr X = 4 Omega`

`i= (5)/(5) = 1 A`.
