Here's a tricky one... A resistor is in series with an inductor, with the current (I) lagging behind the voltage (V) by 60degrees. I am given the impedance (Z) of the circuit, which is 350ohms. How the heck can I find the resistance (R) and the inductive reactance (XL) when I know only the impedance and the phase angle. XL=2pifL Z=sq.root(R^2+(XL-XC)^2 What equation would I use...since I don't know f, L, or C!?! Thanks!
