A certain current on passing through a galvanometer produces a deflection of 100 divisions. When a shunt of one ohm is connected, the deflection reduces to 1 division. The galvanometer resistance is

Options

  1. A100
  2. B99
  3. C10
  4. D9.9

Correct answer

B. 99

Step-by-step solution

Shunt is connected to the galvanometer aligned i_ g &= i S S+G 1 &= 100 1 (1+G) G &=99 aligned G=99
