Question

1) What is the secondary voltage of a transformer which has a primary voltage of 20 volts, primary winding of 40 turns with a secondary winding of 120 turns?

2) The primary voltage of a transformer is 10 volts and the primary winding is 20 turns. If the secondary winding is 100 turns, what is the secondary voltage?

Answer 1

Answer:

1- secondary voltage 60 volts. 2- secondary voltage =50 volts

Explanation:

l1/l2=v1/v2 similarly, 10/v2= 20/100

v2= 10×100/20

v2= 50 volts

=> 40/120= 20/v2

=> 40×v2= 120×20

=> v2 =20× 120/40

=> v2= 60 volts
