Electro Magnetic Induction And Alternating Currents Question 53
Question: The value of the current through an inductance of $ 1H $ and of negligible resistance, when connected through an ac source of 200 V and 50 Hz, is [AFMC 2000]
Options:
A) 0.637 A
B) 1.637 A
C) 2.637A
D) 3.637 A
Show Answer
Answer:
Correct Answer: A
Solution:
$ i=\frac{V}{X_{L}}=\frac{200}{\omega L}=\frac{200}{2\pi \times 50\times 1}=0.637,A $
