A galvanometer of resistance 100 requires 10 A current for full scale deflection. Now a resistance of 1 is connected to convert it into an ammeter. The minimum current required to obtain full scale deflection is

Options

  1. A101 ~mA
  2. B1 01 ~mA
  3. C11 0 ~mA
  4. D10 1 ~mA

Correct answer

B. 1 01 ~mA

Step-by-step solution

aligned I &= ( G+S S ) I_ g &= ( 100+1 1 ) 10 A &=1010 A=1.01 ~mA aligned
