Question
Physics Question on Electromagnetic induction
A 50 Hz AC current of crest value 1 A flows through the primary of a transformer. If the mutual inductance between the primary and secondary is 0.5 H, the crest voltage induced in the secondary is______.
Fill in the blank with the correct answer from the options given below.
A
75 V
B
150 V
C
100 V
D
200 V
Answer
150 V
Explanation
Solution
Using the formula for induced voltage in a transformer V = M * dI/dt, the crest voltage is calculated to be 150 V.
