Two similar galvanometers are covered into an ammeter and a milliammeter. The shunt resistance of ammeter as compared to the shunt resistance of milliammeter will be

Options

  1. AZero
  2. BMore
  3. CLess
  4. DEqual

Correct answer

C. Less

Step-by-step solution

(i-i_g ) s=i_g G aligned & is = ig ( ~h + s ) & i = ig ( ~g ~s +1 ) aligned More 'S', less i So milliammeter will have more shunt resistance.
