Answer:
The crest voltage induced in the secondary is 100 V
Explanation:
When ac current changes from positive maximum value to negative max. value, then
Time taken is given by the equation as follows
dt=T/2 =1/2 v = 1/(2×50)=1/100 s
e=M (dI/dt) = 0.5×(2/1/100)=100 V
The value of crest voltage induced in the secondary is 100 V
