MHT CET 2026 Physics question
Alternating current of peak value A flows through the primary coil of a transformer. The coefficient of mutual inductance between primary and secondary coils is 1H. The peak value of induced e.m.f. in the secondary coil is (Frequency of a.c. = 50 Hz)
Answer: (C)
Solution
For in the primary, the emf induced in the secondary is , so the peak value is . Substituting: $ =
