I've observed a lack of much-needed rap lyric for Circuit Theory and I made one! This is what I've done for Circuit Theory:

Think of a circuit, of any kind

When you're in USyd state-of-mind

A resistor to limit the current

Too much of which, it’ll be burnt

Take an ammeter, measure the flow

Through a light-bulb, you get the glow

Kirchhoff laws and zero-sum games

Mesh, node, graph, it's full of names

Thévenin, Norton, dualité

Impedance, admittance, réalité

DC-blocking capacitance

L di/dt and reactance

RC-pass-filters, low and high

Band-pass filter corners tie

Sine-excitation and phasor

Please! ... deflect that laser
