>>13067898I have a basic sense for how a capacitor works as an electronic component, and how it behaves impedance-wise. Visualizing it as a small chargeable battery with close-to-zero internal resistance explains most of its basic properties in a way that make sense to me.
I can see how as a charge-holding thing, it charges when connected to a voltage source stronger than its current charge level, and discharges when connected to a voltage source weaker than its current charge level; and that its rate of charging (and therefore, its current draw) are proportional to the derivative of supply voltage (assuming a perfect voltage source, and zero internal resistance of the capacitor). Which for a perfect AC circuit, is equivalent to a phase-shifted resistance, AKA a complex impedance -- but that is a neat abstraction of its fundamental behavior, which is a current draw proportional to derivative of voltage, which just happens to equal a phase shift for sine-shaped supply voltages.
I can also see why in a DC circuit, when wired in sequence it effectively functions as an insulator (once charged, no charge will flow through it), and in parallel it functions as a supply buffer; and when in an AC circuit, when wired in sequence it effectively functions as a conductor as long as it capacity is large enough relative to the circuit current divided by frequency, and in parallel it's a thing that just sits there charging and recharging, which affects power factor while not doing much else.
I don't have a similar feel for how an inductor works. I know it stores energy in the magnetic field, and that its behavior, algebraically, is akin to the negative of a capacitor, with current equal to minus the derivative of the voltage under ideal conditions. But I don't understand what is happening physically here, and how its basic physical behavior lead to the algebraic properties we're all used to.
Could you explain this shit?
