Homework Statement
Find the impedance (Z) of the circuit in the shown figure (R and L in series, and C in parallel with them). A circuit is said to be in resonance if Z is real, find ω in terms of R, L, and C?
Homework Equations
VR= RIeiωt
VL= LiωIeiωt
VC= (Ieiωt)/(iωc)
What I mean by I is I (not) H didn't know how to write it and i imaginary number, I hope the I wrote the equations clearly.
The Attempt at a Solution
What I think about is:
1. Find Z.
2. Put Z in term of x+iy.
3. If Z is real then y=0.
4. find ω from y=0.
If that correct I should find Z, but I'm not sure about it.
first I found Zseries for R & L = R+iωL
then Z = Zseries || ZC
Am I right? or there are some specific formulas as if all R, L & C are in series?
