Q. In step-up transformer, relation between number of turns in primary $(N_{P})$ and number of turns in secondary $(N_{S})$ coils is

J & K CETJ & K CET 2008Alternating Current

Solution:

In step-up transformer, number of turns in primary coil is less than the number of turns in secondary coil. ie, $ \frac{N_{s}}{N_{p}} > 1$
