I went through the same thing with electronics being taught the water model then you’re told to throw that out because AC doesn’t act like water.
I say bullshit! My instructors didn’t understand AC well enough IMO
Once you understand AC well enough you realize it still applies to the water model of electrical flow. Induction is inertia, capacitance is pipe deformation from pressure.
When you slam a valve shut in an old house you make a massive pressure spike (inductive field collapse, flyback voltage spike) which oscillates within a resonant circuit when the pipes absorb that extra pressure by expanding, then releasing that spike back into inertia, which makes a smaller spike back into hoop stress until friction (resistance) saps all of the energy out of the circuit.
You can make a DC-DC boost converter by opening and closing a valve really quickly on a long pipe and feed the pressure spikes into a check valve.

Wish I had you as a teacher
