RE: Is a CW coil a TEsla coil, was tesla's colorado lab

John F, All -

Tesla was looking for ultra high voltages. For a fixed amount of energy only
a dampened sine wave can be used to obtain the maximum voltage and power in
an air core transformer (Tesla coil). The Log Dec should be the maximum
possible. In the design of a Tesla coil the relationship between the Log Dec
and the Q factor is a compromise.

  Log Dec x Q factor = Pi

Bill,

No reason why a tube coil (CW) would not be a Tesla coil.  Tesla
experimented with CW.  THere was a very long thread on this
a couple years ago.  The consensus was that a CW coil is indeed
a Tesla coil.
