While solving the below circuit:
The solution is as shown below:
I noticed the following while analyzing it:
how a pure resistance both the voltage across it and current through it have imaginary parts?
What do these imaginary parts represent?
Similarly for a pure reactive load (inductive) what does the real part of the voltage Vx mean?
