Question

The current in the secondary coil of a transformer is 1 A and that in the secondary is 0.5

Answer 1

Answer:

transformer ratio :

voltage in primary coil / voltage in secondary coil= current in the secondary coil / current in primary coil

= ( 1/0.5) =2

now ,

voltage in primary coil / voltage in secondary coil = ? V / 200 = 2

=voltage is primary coil V = 400 V
