Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <TeraJoule-at-aol-dot-com> I have a question for the list.... What does each of the components of the tesla coil do? Meaning, what is their purpose in the circuit? For example, what does the capacitor do in the circui, or what does the spark gap do? Thank you for your time... I'm just trying to understand it all. ~Alex
