A series RLC circuit has a 0.19 mF capacitor, a 16 mH inductor, and a 10.0 resistor, and is connected to an ac source with amplitude 9.0 V and frequency 60 Hz.
(a) Calculate the voltage amplitudes VL, VC, VR, and the phase angle phi .
VL = V
VC = V
VR = V
angle phi= °
angle phi =
The Attempt at a Solution
I calculated XL=wL=2pi60Hz*16x10^-3 = 6.03
XC = 1/wC = 1/2pi*60Hz*0.19*10^-3 = 13.96
angle phi =tan-1 (XL-XC/R) which is tan-1(6.03-13.96/10 ohms) = -38.41 degrees.
I have been unable to find VL, VC and VR. I tried translating 9V amplitude into rms and got 6.36V. I tried using Vrms=IrmsR to find Irms but have been unsuccessful. Any ideas?
