This Design Idea applies a noveltopology to an oscillator. It usesa series-connected LC (inductive-capacitive)tank circuit to give the circuita higher tuning range than circuitsthat use a parallel-LC ...

If you are thoroughly grounded — no pun intended — in LC circuits, you probably won’t learn anything new. However, the animations are worth watching, just to admire them, if nothing else.

Know your way around an electric circuit? Show that you know your series circuits from your parallel circuits with BBC Bitesize.

In So you think you understand transmission lines, I offered a seeming paradox about a property of transmission lines. If you look at the input impedance of a uniform transmission line, open at the ...
