A moving coil galvanometer has resistance `50 Omega` and it indicates full deflection at 4 m A current. A voltmeter is made using this galvanometer and a `5k Omega` resistance. The maximum voltmeter, will be close be :

10V

40V

15V

20V

Text Solution

Verified by Experts

`V=j_g[R_g+R]=4 times 10^-3 [50+5000]=20.2` volt=20 volt
