**[SOLVED] Finding RLC from Freq and Impediance (AC Ckt)**

## Homework Statement

1. Determine the values of R, L and C in an AC circuit to satisfy the following criteria:

(i) the impedance at resonance is 5 k Ohms

(ii) the resonant frequency is 60 Hz (USA standard)

(iii) the voltage lags the current in the circuit by 2.8 degrees at a frequency of 50

Hz (the European standard).

(iv) Draw the phasor diagram for the impedance at 50 Hz.

2. Find the impedance and phase angle for this circuit at f = 1 kHz. Then draw the impedance diagram at this frequency.

## Homework Equations

R: Xr=R

L: Xl=wL

C:Xc=1/wC

## The Attempt at a Solution

Well i know that Frequency = w/2(pi) so i can plug in 60hz=w/2(pi) to get a angular frequency=376.99 rad/s and since w=2(pi)/T i can get a time of .0166seconds...

but i get stuck after that point, cause i can't find equations that relate any more variables without the others.
