A moving coil galvanometer has a resistance of 40 Ω. It gives a full scale deflection with a current of 2 mA. How is to be modified to convert it to a voltmeter of 5 V range by connecting some resistance? |
1230 Ω connected in series with galvanometer 2460 Ω connected in series with galvanometer 1230 Ω connected in parallel with galvanometer 2460 Ω connected in parallel with galvanometer |
2460 Ω connected in series with galvanometer |
The correct answer is Option (2) → 2460 Ω connected in series with galvanometer |
