Question

Two pure inductors each of self inductance L are connected in parallel but are well separated from each other. The total inductance is

  1. 2 L    
  2. L    
  3. fraction numerator L over denominator 2 end fraction    
  4. fraction numerator L over denominator 4 end fraction    

The correct answer is: fraction numerator L over denominator 2 end fraction


    Inductors obey the laws of parallel and series combination of resistors.
