In the given circuit, the voltmeter records 5 volt. The resistance of the voltmeter in `Omega` is

A

200

B

100

C

10

D

50

Text Solution

Verified by Experts

The correct Answer is:
B
Total potential of `10 V` equally distributes between`50 Omega` and other parallel combination of `100 Omega` and voltmeter. Hence, their net resistance should be same. Or
`(100xxR)/(100+R)=50`
`:. R=100 Omega=`resistance of voltmeter
