NEET Physics AC Voltage MCQ Question
If an ideal transformer is 100% efficient and the primary coil has 100 turns with an input voltage of 200 V, what is the secondary voltage if the secondary coil has 50 turns?
100 V
200 V
400 V
50 V
Correct Answer
Detailed Explanation
The voltage ratio in a transformer is given by Vp/Vs = Np/Ns. For 100 turns on the primary with 200 V, and 50 turns on the secondary, Vs = (50/100) * 200 V = 100 V.
