A galvanometer has resistance 80 and it is shunted with resistance 20 . If 20 % of the main current flows through galvanometer, then what is the value of main current?

Options

  1. A0.2 A
  2. B0.8 A
  3. C1 A
  4. D1.2 A

Correct answer

C. 1 A

Step-by-step solution

aligned & I=I₁+I₂ & I₁=0.2 I I ₂=0.8 I & Also, I ₁ G = I ₂ ~S & 0.2 I 80=0.8 I 20 & I =1 ~A aligned
