In my Intro to EE class we have a homework assignment with the following problem:
I think I finished part a but want to make sure that I am doing the problem correctly before I move on to the next part.
The current is specified as a cosine function of time. It has a frequency, so there's your ω for determining impedances. Its phasor will be just the magnitude of the cosine function since there's no phase shift involved.but the given current is in terms of t and impedances are in terms of s or jω
what do I do about that?
Yes, that looks much better!I found where I made the error, it was when I plugged in Va in terms of V2 into (1), so after solving it (correctly this time I think) I got
does that look right?
