In case there are students who are struggling in the beginning circuits course, I am providing this little jingle to help you remember stuff.

You should be able to figure out the tune once you start reading.

Verse 1
Ohmic Donald had a circuit.
E-I-E-Diode
And on that circuit he had a …
… resistor!
E-I-E-Diode
With a voltage drop here and a voltage drop there.
Here a drop, there a drop, everywhere a drop-drop.
Ohmic Donald had a circuit.
E-I-E-Diode

Verse 2
Ohmic Donald had a circuit.
E-I-E-Diode
And on that circuit he had a …
… capacitor!
E-I-E-Diode
With a stored charge here and a stored charge there.
Here a charge, there a charge, everywhere a charge-charge.
Ohmic Donald had a circuit.
E-I-E-Diode

Verse 3
Ohmic Donald had a circuit.
E-I-E-Diode
And on that circuit he had a …
… inductor!
E-I-E-Diode
With magnetic flux here and magnetic flux there.
Here a flux, there a flux, everywhere a flux-flux.
Ohmic Donald had a circuit.
E-I-E-Diode

Verse 4
Ohmic Donald had a circuit.
E-I-E-Diode
And on that circuit he had a …
… transistor!
E-I-E-Diode
With a switch-switch here and a switch-switch there.
Here a switch, there a switch, everywhere a switch-switch.
Ohmic Donald had a circuit.
E-I-E-Diode

Any other components that a young student of electronics should know?

And yes, I know that inductors deal more with Faraday’s Law than with Ohm’s Law. If we stuck only with Ohm’s Law, there would not be very many verses.
