Question

An inductor L, a resistance R and two identical bulbs B1 and B2 are connected to a battery through a switch S as shown in the figure. The resistance of coil having inductance L is also R. Which of the following statement gives the correct description of the happenings when the switch S is closed?

  1. The bulb B subscript 2 end subscript lights up earlier than B subscript 1 end subscript and finally both the bulbs shine equally bright.    
  2. B subscript 1 end subscript light up earlier and finally both the bulbs acquire equal brightness.    
  3. B subscript 2 end subscript lights up earlier and finally B subscript 1 end subscript shines brighter than B subscript 2 end subscript    
  4. B subscript 1 end subscript text  and  end text B subscript 2 end subscript light up together with equal brightness all the time.    

The correct answer is: The bulb B subscript 2 end subscript lights up earlier than B subscript 1 end subscript and finally both the bulbs shine equally bright.
