Resistance of voltmeter is 10000Omega to...

Resistance of voltmeter is `10000Omega` to increase range of voltmeter from `25 V`, resistance connected in series is

A

`990Omega`

B

`9990Omega`

C

`90000Omega`

D

`90Omega`

Text Solution

Verified by Experts

The correct Answer is:
C

`G=10000 Omega , n =(V)/(V_g)=(250)/(25)=10, R=?`
` R=G(n-1)=10000(10-1)`
`=90000 Omega` .
