NEET Physics AC Voltage MCQ Question
Type: MCQ-numerical-Hard-Class 12
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?
A
100 V
B
200 V
C
400 V
D
50 V
Correct Answer
Option A
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.
