Thermodynamics was a pretty life changing learning experience for me. I also threw in a little heat transfer needed to understand - but really that's more looking at the processes of conduction, convection and radiation rather than energy flow and phase changes (which is classic TD).

3 Laws that help you understand a lot of things:

Conservation of Mass
Conservation of Energy (First Law of Thermodynamics)
Entropy (Second Law of Thermodynamics)

and if you want to get weird, you apply those principles to charges on circuits:

Kirchhoff's Current Law (conservation of charge and energy)
Kirchhoff's Voltage Law (conservation of energy)

and the odd one:

Ohm's Law

And then you know 90% of electrical circuits.
