Some not so useful useful but cool sounding and true analogies I have used during my office hours while teaching undergrads about circuits:

*Charging a capacitor is like falling out of an airplane.*

*“Charging” an inductor is like a bunch of uranium decaying.*

*A circuit with an inductor and a capacitor is like a pendulum.*

*A circuit with an inductor, capacitor, and resistor is like a pendulum in oil.*

*A circuit with an inductor, capacitor, resistor and AC power source is like pushing a kid on a swing.*
