Question

A transformer has 200.0 turns in its secondary coil and 120.0 turns in its primary coils. The primary coil is connected to a 80.00 V power supply. If 3.50 A flows in the primary coil, then how much current is there in the secondary coil

Answer 1

No.of primary turns/no.of secondary equal to current in primary /current in secondary therefore 200/120=3.50/C.in secondary =2.1A
