To use the milliammeter of the previous question as a voltmeter of range `10 V`, a resistance `R` is placed in series with it. The value of `R` is

A

`9 Omega`

B

`99 Omega`

C

`999 Omega`

D

`1000 Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
`V = i_g (R + G)`
`10 = 10 xx 10^-3(R + 0.9) rArr R = 999 Omega`.
