A moving coil galvanometer of resistance 20 ohm produces a full-scale deflection when a current of 0.05 A is passed through it. How will you convert this galvanometer into a voltmeter reading up to 240 V?
1
By connecting resistance of 4790 ohm in series with the galvanometer
2
By connecting resistance of 4780 ohm parallel to the galvanometer
3
By connecting resistance of 9580 ohm parallel to the galvanometer
4
By connecting resistance of 4780 ohm in series with the galvanometer
