Homework Statement
I have ##V = 25cos(1000t)## and ##I = Acos(1000t)## for a circuit, I'd like to make those into phasors.
Homework Equations
##V = Acos(\omega t+\theta)## ##\leftrightarrow## ##V = Ae^{j\theta}##
The Attempt at a Solution
It seems like this is relatively simple, but that seems to be my problem, these are my two confusions:
##V = 25cos(1000t) = 25e^{j(1000t)}## ?
Or is it:
##V = 25cos(1000t) = 25e^{0}## ?
I'm not quite sure which route to go towards, could anyone possible point me towards the right direction or explain why it's one over the other? My main confusion is that if I change ##V = 25e^{j(1000t)}## back into it's cosine and sine components (using Euler's Identity) I end up with:
##V = 25cos(1000t)+jsin(1000t)##
...is the imaginary part ignored?
