Homework Statement
Question 2 on this paper:
http://www.eng.cam.ac.uk/teaching/past_papers/examples_student/examples_IA/P3_LCD_Q/1ap3lcdq003
Homework Equations
Z = V/I
V=L di/dt
The Attempt at a Solution
for part a of the question:
I began with V = Vo cos(wt)
And I = Io cos (wt + k)
I expressed them as exponentials' real parts using Euler's relation:
Z = V/I
So, Z = [Vo (e^(-jk))]/Io
I don't know what to do further.
I've looked around the internet and apparently that leads to
Z = R + jX
So, the answer for the part a would be 10 + j10
But how?
Thanks
