I'm still stuck on this task:
And I'm trying to calculate Vth. I've calculated:
My problem now is that I want to convert from rectangular form to polar form for 100j/100 + 100j. I can't seem to get it right. I tried multiplying with the conjugate, however I just got (j). I want to convert it to polar form so that I can multiply the amplitudes and add the angles. However I'm stuck.
Could someone help?
Update: I solved the upper part. Now I need help with time-domain. Please look below:
I've got a hard time understanding how to calculate the time domain. I've found the Vth and Zth like so:
Note: Ignore the white markings, it was written in swedish, therefore I tried to hide it so it wouldn't led to confusion.
I don't know how to find the angle and how to proceed with finding the time domain so that I can draw a schematic of it.
I would appreciate some help. Thanks!
