For the circuit shown below, let vS(t) = 575 cos(2?60t + 30o), R1 = 35 ?, R2 = 53 ?, L = 76 mH, C1 = 117 ?F, C2 = 106 ?F

(a) Find impedances ZL, ZC1, ZC2, and phasor VS for vS(t).

(b) Find the equivalent impedance Za of parallel combination of ZC2 and ZR2 + ZL.

(c) Find the total impedance Zt seen from the voltage source.

(d) Find the phasor for the current I.

(e) Find the phasor for Vo across the capacitor C2.




ZL = j?L = j28.6513 ?
ZC1 = 1/(j?C1) = -j22.6716 ?, ZC2 = 1/(j?C2) = -j25.0244 ?
Za = (R2 + ZL) || ZC2 = 11.7604 - j25.8292 ?
Zt = R1 + ZC1 + Za = 46.7604 - j48.5008 ?
I = Vs/Zt = 2.058 + j8.283 A
Vo = Za×I = 238.1454 + j44.2542 = 242.2224?105.2711o V
vo(t) = 242.2224 cos(2?60t + 105.2711o) V
