Question

The ratio of secondary to the primary turns in a transformer is 3:2. If the power output be P, then the input power neglecting all losses must be equal to

  1. 5 blank P  
  2. 1.5 blank P  
  3. P  
  4. fraction numerator 2 over denominator 5 end fraction P  

The correct answer is: P


    If there are no losses then p subscript i end subscript equals p subscript 0 end subscript
