A transformer has a primary coil with 50 turns and a secondary coil with 25 turns. If the primary coil has a current of 2 A and the secondary coil has a resistance of 5 Ω, what is the output voltage of the transformer?
Q1. A transformer has a primary coil with 50 turns and a secondary coil with 25 turns. If the primary coil has a current of 2 A and the secondary coil has a resistance of 5 Ω, what is the output voltage of the transformer?
Answer: 50 V
Explanation: The output voltage of the transformer is given by the turns ratio, which is the ratio of the number of turns in the primary coil to the number of turns in the secondary coil. This results in a turns ratio of 2:1, and since the primary coil has a current of 2 A and the secondary coil has a resistance of 5 Ω, the output voltage will be 50 V.
