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
  • a)
    2.535 × 103
  • b)
    4.005 × 103
  • c)
    1.985 × 103
  • d)
    2.045 × 103
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
When a current of 5 mA is passed through a galvanometer having a coil ...
ig = 5 × 10–3 A
G = 15 Ω
Let series resistance be R.
V = ig (R + G)
10 = 5 × 10–3 (R + 15)
R = 2000 – 15 = 1985 = 1.985 × 103
