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 1 H. the peak e.m.f. induced in secondary coil is (Frequency of a.c. is 50 Hz)
Answer: (D)
Solution
Let the primary current be with A and rad/s. The induced emf in the secondary is , so its peak value is
