Galvanometer to AmmeterMediumQuestion 31641

Question

To convert a galvanometer (resistance G, full-scale deflection current I_g) into an ammeter for range I, a shunt resistance S is connected:
  1. A
    In series with galvanometer
  2. B
    In parallel with galvanometer
    Correct
  3. C
    Replacing the galvanometer
  4. D
    Between galvanometer and battery

Correct answer

In parallel with galvanometer

Explanation

Shunt S is connected in parallel so most current bypasses the galvanometer. S = I_g×G/(I−I_g).
