A galvanometer of 50 Ω resistance has 25 divisions. A current of 4 x 10-4 A gives a deflection of one division. To convert this galvanometer into a voltmeter having a range of 25 V, it should be connected with a resistance of:
- 2500 Ω as a shunt
- 245 Ω as a shunt
- 2550 Ω in series
- 2450 Ω in series
Answer
(D) 2450 Ω in series
