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
