Explanation The transformer is a device which can change a low voltage of high current into a high voltage of low current and vice versa. The induced emf. is directly proportional to flux linkage with each turn of the primary and secondary at any instant. The transformer ratio thus obtained is used to calculate voltages and current in the primary and secondary coils of the transformer. Calculation of number of turns of a primary coil The voltage in primary winding V Pr i m a r y = 12 0 V Voltage in secondary winding V sec o n d a r y = 3 V Number of turns in secondary coil N sec o n d a r y = 60 Formula used: We know for a transformer the voltage across the primary and secondary are related by V sec o n d a r y V Pr i m a r y = N sec o n d a r y N Pr i m a r y (I) Voltage in primary coil is calculated is N Pr i m a r y = N sec o n d a r <
