While working in a lab this summer, I've been reading up on impedance and AC circuits as much as I can, considering I have to present at the symposium here in August. I'm really confused about a few...parts of impedance, for lack of a better term.
How does frequency affect impedance, in general?
I know: Z = R + jX, Z = R + ZL + ZC = R + j(XL - XC) and XC = 1/[tex]\omega[/tex]*C, XL = [tex]\omega[/tex]*L
But a more general statement would help when it comes to explaining/summing everything up on how frequency affects impedance, especially when explaining it to people who have never studied impedance in depth but have only heard the term before.
How does frequency affect resistors, capacitors, and inductors? Is it just the equations for impedance for each of these?
And when I see |Z| and [tex]\phi[/tex], am I to think of polar plots of impedance? Or something to that effect?
Sorry if I repeated any questions already answered here. I did a search and found nothing. :)
