A step down transformer changes the voltage from 2200 V to 220 V. Its primary coil has 5000 turns. If the efficiency of the transformer is 80% and output power is 8 kW, then find out the: (i) NS (ii) IS (iii) IP (iv) input power.
Potential in primary coil (VP)= 2200 V Potential in secondary coil (VS) = 220 V Turns in primary coil (NP)= 5000 Efficiency (η) = 80% Output power Pout = 8 kW By the formula:
