Pspice RLC AC analysis
Hello
here is my pspice code and circuit that I want to simulate.
Code:
Hello the world
V 1 0 AC 1V
R 1 2 50
L 2 3 .02H
C 3 0 150nf
.ac LIN 4901 100Hz 5kHz
.Probe
.END
as you see the probe windows we have this output(Resistor current and Capacitor voltage)
So we do some calculation
|I|=.02 in resonance frequency (2.9Khz)
|Xc|=1/(2900*150*10^(-9))=2298.8
|Vc|=|I|*|Xc|=.02*2298.8=45.97
but according the V(3)(Capacitor voltage) we have 7.3 at resonance frequency.
other calculation:
we know the Capacitor voltage at resonance frequency is about |VC|=Q*|Vin |
|Vc|=|I|*|Xc|=(|Vin|/R)(1/w0C)=|Vin|*Qc
w0=2900hz
QL=(w0*L)/(R)=1.16
|VC|=Qin*|Vin=1.16*1=1.16
Or
w0=2900hz
QC=(1)/(w0CR)=45.97
|VC|=Qin*|Vin=45.97*1=45.94
If there is no problem could you tell me what are my mistakes?

Sorry I found my problem
I didn't substitute the resonance frequency into w=2*Pi*F
