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

• A. 0.637 A
• B. 1.637 A
• C. 2.637A
• D. 3.637 A

Answer 1

Answer: (A)

0.637 A

Answer 2

$i = \frac{V}{X_{L}} = \frac{200}{\omega L} = \frac{200}{2\pi \times 50 \times 1} = 0.637A$
