A moving coil galvanometer has resistance `50 Omega` and it indicates full deflection at 4 mA current. A voltmeter is made using this galvanometer and a `5 k Omega` resistance. The maximum voltage, that can be measured using this voltmeter (in volts) will be __________.

Text Solution

Verified by Experts

The correct Answer is:
20.2
`V=i_(g)[R_(g)+R]`
`=4xx10^(-3) [50+5000]=20.2 ` volt
