(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 39.5 uF capacitor is connected to a 47.0 ohm resistor and a generator whose rms output is 25.2 V at 60.0 Hz. Calculate the rms current in the circuit.

(also asks for voltage drop across resistor, capacitor and the phase angle for the circuit, but I mostly want to get the first one first)

2. Relevant equations

I=current, V=voltage, R=resistance, f=frequency

Irms=1/sqrt(2)*Imax

Irms=delta Vc, rms/Xc

Xc=1/(2pi*f*c)

delta Vc,rms=Irms*Xc

and then I start going in circles

Other formulas that might be appropriate:

Vmax=Imax*Z

Z=sqrt(R^2+(Xl-Xc)^2)

Xl=2pi*f*L

L=?? not given in this problem

Power average=Irms^2*R

3. The attempt at a solution

combining lots of these formulas trying to come up with the correct Vrms has proven unsuccessful. I came up with 17.819 A, .37515 A, .21739 A, none of which were right. None of them were successful and I don't remember or care to explain how I got them precisely because I wasn't confident in those anyway.

Overall I still haven't been able to link my given information directly to the answer I need
