To donate:

We will learn what to do when 2 lines are parallel and we didn't realize it, and when lines don't intersect there is no solution.

Hey Sir, for AC Circuits, when the qts tells us to find the total impedance Z of the circuit, do we have to write the final ans in polar form with the magnitude and phase angle included? Also, when finding voltage drop across an inductor/capacitor, do we have to take into account the phase angles when taking the current through the inductor/capacitor multiplied by the reactance of the of the inductor/capacitor?
