Alternating current of peak value ( 2 ) 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 (Frequency of a.c. =50 ~Hz )
Options
- A50 V
- B150 V
- C100 V
- D200 V
Correct answer
D. 200 V
Step-by-step solution
aligned & =2 v=2 (50)=100 & I=I₀ t & d I d t =I₀ t aligned Maximum value of dI dt = I ₀ gathered = 2 (100 )=200 ~A / S E = L dI dt =1 200=200 ~V gathered
