One of the oldest circuits in all of hamdom is the tank circuit, which in its various incarnations has presented a profound mystery to many hams. In this Adventure, we hope to take some of the mystery out of tank circuits in general, and the commonly perplexing Pi-network in particular. As is often the case, we’ll also learn some interesting physics in the process. We will also determine whether or not you actually BELIEVE Kirchhoff’s current law (KCL).
As some of you may recall, a while back, I presented this paradox of sorts in the form of a simple question, based on the schematic in Figure 1:
Is the circuit in Figure 1 a series or parallel circuit?
Your answer is wrong.
The reason it’s wrong is because there isn’t
