Question

In step-up transformer, relation between number of turns in primary left parenthesis N subscript p end subscript right parenthesis and number of turns is secondary left parenthesis N subscript s end subscript right parenthesis coils is

  1. N subscript s end subscriptis greater than N subscript p end subscript  
  2. N subscript p end subscript is greater than N subscript s end subscript  
  3. N subscript s end subscript is equal to N subscript p end subscript  
  4. N subscript p end subscript equals 2 N subscript s end subscript  

The correct answer is: N subscript s end subscriptis greater than N subscript p end subscript


    In step-up transformer, number of turns in primary coil is less than the number of turns in secondary coil.
    i e comma fraction numerator N subscript s end subscript over denominator N subscript p end subscript end fraction greater than 1
