V

1

Where,

N

1

=Number of turns in the primary

N

2

=Number of turns in the secondary

V

1

=Primary Voltage

V

2

=Secondary Voltage

Answer 2

Answer:

The transformer works on basic principles of electromagnetic induction and mutual ... K is called the voltage transformation ratio, which is a constant.
