Question

The reactance of an inductance of $0.01\, H$ to a $50 \,Hz$ A.C. is

• A. 1.04 $\Omega$
• B. 6.28 $\Omega$
• C. 0.59 $\Omega$
• D. 3.14 $\Omega$

Answer 1

Answer: (D)

3.14 $\Omega$

Answer 2

Given: Inductance $(L)=0.01 H$ and frequency $(n)=50 Hz$. We know that the reactance $\left(X_{ L }\right)=\omega L=$ $2 \pi n \times L=2 \times \pi \times 50 \times 0.01=3.14\, \Omega$
