Hello guys,
First off thanks for helping me with my last question-much appreciated! im curently having difficultly with a R-LC Parrallel and series resonance (L with winding R) question, having looked through previous threads and lessons im still not clear on the topic.Heres where i am so far;
Series R-LC circuit resonates at 2251Hz
Parallel R-LC circuit resonates at 2228Hz at 25Vrms I is found at 5mA
Find vaules of components
R=V/I
R=5kΩ
R=Ztotal
I=V/R Branch IL =2.5mA Ic =2.5mA Itotal= 5mA
Xc=V/Ic = 1kΩ
At Resonance Xl=Xc
ω=2∏f
ω=14k rads
Ic=ωCV
C=7.14nF
Xl=2∏fl
L=14H
Vaules of R L C have been found using the above(apolgises for the layout)
When vaules subsited into F=1/2∏rootLC it isnt my resonance vaule which means my caculations must be out somwhere having worked through again im still non the wiser.
Am im right in keeping Vs in rms vaule?
Will Isupply be the same as the parrallel cct vaule?
Any help would be greatly received!
Many Thanks,
Rubberfrog
