Question
The primary winding of a transformer has 100 turns and its secondary winding has 200 turns. The primary is connected to an ac supply of 120 V and the current flowing in it is 10 A. The voltage and the current in the secondary are
- 240 V, 5 A
- 240 V, 10 A
- 60 V, 20 A
- 120 V, 20 A
The correct answer is: 240 V, 5 A
