When a current of 5 mA is passed through a galvanometer having a coil of resistance 15 Ω , it shows full scale deflection. The value of the resistance to be put in series with the galvanometer to convert it into a voltmeter of range 0 – 10 V is

1. 1.985 × 10 3 Ω
2. 2.045 × 10 3 Ω
3. 2.535 × 10 3 Ω
4. 4.005 × 10 3 Ω

Correct answer: 1.985 × 10 3 Ω
