Electro Magnetic Induction And Alternating Currents Question 11
Question: In a circuit containing an inductance of zero resistance, the e.m.f. of the applied ac voltage leads the current by [CPMT 1990]
Options:
A) 90o
B) 45o
C) 30o
D) 0o
Show Answer
Answer:
Correct Answer: A
Solution:
In a pure inductor (zero resistance), voltage leads the current by $ 90^{o}i.e.\pi /2. $
