If only 2 % of the total current passes through an ammeter having coil of resistance ^ R ^ then the resistance of the shunt of an ammeter is

Options

  1. A49 R
  2. BR 50
  3. CR 49
  4. D50 R

Correct answer

C. R 49

Step-by-step solution

I _ g I = 2 100 = 1 50 I _ g I = S S + R 1 50 = S S + R S + R =50 ~S R =50 ~S , R =49 ~S or S = R 49
