Question

n the given figure, when galvanometer shows no deflection, the current (in ampere) flowing through 5 capital omega resistance will be

  1. 0.5    
  2. 0.6    
  3. 0.9    
  4. 1.5    

The correct answer is: 0.6


    Let current through 5 capital omega resistance be i. Then
    i cross times 25 equals left parenthesis 2.1 minus i right parenthesis 10Þ i equals fraction numerator 10 over denominator 35 end fraction cross times 2.1 equals 0.6 A
