 Homework Statement:
 Need to determine capacitor value so that the circuit is in resonance
 Relevant Equations:

E=21∠0º
ω=10^3 rad/s
R1=10Ω
R2=40Ω
L=100mh
C=?
L=100mh=0.1H
ω=10^3 rad/s > f = 159Hz
XL= ωL= 2πfL= 2π*159*0.1= 99.90 Ω
Z parallel = [(XL∠90º)*R2] / [(XL∠90º)R2]= 37.13∠21.8º
XC= 1/ωC= 1/(2 π f C)
I don't see how I am supposed to get to C
