RE: Direct current coils
Paul
All coil tank circuits containing capacitors and inductors are designed to
resonate at a matching frequency with the coil (primary and secondary) and
thus, are indeed subject to high frequency AC, power surges, dampened waves
and all sorts of nasty things that capacitors don't really like. A CW coil
capacitor is
some what less stressed, but still challenged.
Even the final filter capacitor ( assuming basic FWB ) in the rectification
circuit must help smooth
out a rising and falling voltage. This capacitor is critical to insure
smooth DC
going to the rotary spark gap or the CW oscillator.
If none of this makes any sense to you, then please pick up one of the
excellent
books written by the list members. Capacitors in a coil circuit are
dangerous. A high voltage
DC filter circuit can be especially deadly, considering the joules of
energy at a high voltage.
There is safety and power in knowledge.
Be safe in your coiling.

Does anyone know where I can obtain plans for a coil that runs off
direct current?
Would the capacitor in a direct current coil be subject to alternating
current?
