Question

5 blank c mlong solenoid having 10 blank o h m resistance and 5 blank m H inductance is joined to a 10 blank v o l t battery. At steady state the current through the solenoid in a m p e r e will be

  1. 5  
  2. 1  
  3. 2  
  4. Zero  

The correct answer is: 1


    In steady state current passing through solenoid
    i equals fraction numerator E over denominator R end fraction equals fraction numerator 10 over denominator 10 end fraction equals 1 blank A
