Hi guys, I am having a bit of a problem finding the Impedance.. Here are my figures below, but I am confused if I use the AC supply frequency which is 50 or the resonant frequency which is 234 x103 . Reactance of the circuit inductance
XL
= 2 Pi x Frequency x Inductance
2 PI x 50 x 0.0232
x10-3
= 7.288 x10-3
Reactance of the circuit capacitance
Xc = 1/2 Pi x Frequency x Capacitance1/2 Pi x 50 x 0.02 x10-6
= 159.15 x103 ImpedanceZ= ((XL –XC) 2)0.5((7.288 x10-3 –159.15 x103)2)0.5
= 159.15 x103
Or Reactance of the circuit inductanceXL = 2 Pi x Resonant Freq x Inductance2 x 234 x103 x 0.0232 x10-3=34.11 Reactance of the circuit capacitanceXc = 1/2 Pi x Resonant Freq x Capacitance1/2 Pi x 234 x103 x 0.0232 x10-6= 1591.54 kHz ImpedanceZ= ((XL –XC) 2)0.5((34.11 –34.00)2)0.5= 0.11 which one is the correct one? and for the secondary, if the Frequency is 50... would I do the same? This would be really helpful, Thanks. Matthew
