Question

A 58 V AC voltage source is connected across a 3.7 H inductor. What is the current through the inductor if the frequency is 63 Hz?

Answer 1

We will have the following:

First:

`x_l=2\pi(63Hz)(3.7H)\Rightarrow x_l=466.2\pi\Omega`

Then:

`\begin{gathered} I=(58V)/(466.2\pi\Omega)\Rightarrow I=0.03960097254...A \\ \\ \Rightarrow I\approx0.04A \end{gathered}`

So, the current is approximately 0.04 A.
