Question

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

Answer 1

The correct approach is "12.56 Ω".

Step-by-step 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)* 100* 20* 10^(-3)`

⇒
`=12.56 \ \Omega`
