How are phasors useful?
If the real component of
corresponds to voltage or current, what does the imaginary component correspond to? Do we ever use the imaginary parts of these complex quantities?
Is the same imaginary mathematical method used if the signal is a sawtooth, step or some other non-sinusoidal function?
How did you go from
to
?
Why does high capacitance correspond to low impedance and vice versa? Physically, why do capacitors increase in impedance when you lower frequency, and vice versa?
Can you clarify reactance? What is it exactly?
Can you add impedances from different circuit elements, i.e. inductors and capacitors?
In an RLC circuit, will the voltages at different points between the different elements have different phases? Shouldn't the voltages across the resistor have the same phase? Should the phase change around the loop be a multiple of
