Hello, all

I got my assignment back and this question was wrong, maybe you can guide me, please because I’m not sure entirety. Help is appreciated. Once i do this question, i pass my Module.

Aplogises if this is the wrong place, but im in dire need of help.

An AC generator produces a voltage of 230<45º volts. It is connected across an impedance of 17.4<-33º ohms.

The supply frequency = 50Hz

Question: Calculate the value of inductance that will make the circuit become series resonant at 50Hz?

I know : 1/2π fc = 2 π fl

I= 17.4 sin33 = 9.47

Capacitance = 1/2 π (50x9.47) = 3.36x10^-6

--

Would it be: 2 π fl > 2 π(50) = 314 ?
