Question

What is the inductive reactance of a 20 mH inductor at a frequency of 100Hz?

Answer 1

Answer:

The correct approach is "12.56 Ω".

Explanation:

The given values are:

Frequency,

f = 100 Hz

Inductor length,

L = 20 mH

Now,

The inductive reactance will be:

⇒ $X_L=2 \pi fL$

On putting the estimated values, we get

⇒       $=2 (3.14)\times 100\times 20\times 10^{-3}$

⇒       $=12.56 \ \Omega$
