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= °

VL= IrmsXL

VC=IrmsXC

VR=IrmsR

angle phi =

3. 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?
