Electro Magnetic Induction And Alternating Currents Question 44
Question: What will be the phase difference between virtual voltage and virtual current, when the current in the circuit is wattles [RPET 1996]
Options:
A) 90°
B) 45°
C) 180°
D) 60°
Show Answer
Answer:
Correct Answer: A
Solution:
If the current is wattless then power is zero. Hence phase difference $ \varphi =90^{o} $
