Solutions

Expert Solution

To solve this problem you have to know about Electrical Impedance and inductive reactance

Step 1.

Definition:

Electrical impedance: is the measure of the opposition that a circuit presents to a current when a voltage is applied.

Inductive reactance: is proportional to the signal frequency and the inductance .

Step 2.

You can calculate the impedance for this equation:

   But the voltage

  If solve L, we have the following
