>>12083129Impedance is complex resistance.
Z = R +- jX
Where R is resistance and X is reluctance.
With DC, a capacitor acts like an open circuit at steady state. It holds a voltage.
With DC, an inductor acts like a closed circuit at steady state. It holds a currents.
The energy stored in a capacitor and inductor have to do with how both voltage and current, the collection of charge and the motion of charge, can not change instantly.
Signals can consist of a DC and AC component, we use analysis techniques to solve for unknowns.
A resistor has a resistance, a capacitor has a negative reluctance and an inductor has a positive reluctance.
With R = 1, C = 1, and L = 1,
R = 1 is our real part, consuming real power, but X_C = -jwC supplies reactive power, while X_L = +jwL absorbs reactive power.
Reluctance is frequency dependent, but AC values have an RMS equivalent used to analyze their DC power loss across real resistances.
