When we next meet, or by email, or both?

How far along that line do you want to go, and what do you know so far, or feel like learning about? Ohms Law (you obviously already know) Skin effect? Complex Impedance? Phase angles? Power factor? Losses in magnetic materials? Kirchoff's law? Thevinin's theorem? Star/delta transformation? Semiconductors (but I don't remember the maths relating to bandgaps)?
