Question
Assume that you have an LRC AC Circuit with one inductor which has an inductance of
L = 81 mH and internal resistance r = 50 described by the LRC Circuit phasor
diagram below.

If your AC Power Supply is tuned to a frequency f = 600 Hz and you measure a Power
Supply rms potential Vps = 3.5 V, a capacitor rms potential Vc = 2.4 V, a (real) inductor rms
potential Vind = 4.5 V, and a resistor rms potential VR = 2.1 V, what is the potential across
the inductor's inductance, V₁?
VL-VC
Hint: Calculate the angular frequency, w, and the inductor's impedance XL = wL. (Make sure you're in
Ohms!) Then, use the expression from your Lab 8 Handout and Calculation sheet for V₁.
