**Henry**, Thursday, March 7, 2013 at 8:36pmIs the inductive reactance of the coil 1200 ohms? If so:

a. Xl = 2pi*F*L = 1200 Ohms.

F=Xl/(2pi*L)=1200/(6.28*0.07)=2728.4 Hz.

b. Xc = 1/(2pi*F*C)

Xc=1/(6.28*2728.4*0.001*10^-6)=58333 Ohms

Z = Xl+ Xc=1200 + (-58333)=-57133 Ohms,

Capacitive. = 57133@(-90) Deg.

I = V/Z = 120/57133=2.1*10^-3A @ 90 Deg.

c. Z was calculated in under b.
