A 120V rms voltage at 2000 Hz is applied to a 6.0mH inductor, a 2.0ìF capacitor and a 200Ù resistor. What is the rms value of the current in this circuit?

Xl = 2pi*F*L = 6.28*2000*0.006 = 75.4 Ohms.
Xc = 1/(2pi*F*C)=1/(6.28*2000*2*10^6) =
39.8 Ohms.
Z = R + (XlXc) = 200 + j(75.439.8) =
200 + j35.6 = 203 Ohms[10.1o]
I=E/Z = 120[0o]/203[10.1o]=0.59[10.1o]
Amps.
