Subject: Re:  HV cap ver 1.1

I personally use a screw driver or clip lead, but capacitors
are not large.  For discharging really large capacitors such
as in a hv transmitter power supplies, a 10k, 10 watt wire wound
should do just fine.  It will dissipate as much as a hundred
watts for a few seconds.  For example, an 0.1 ufd capacitor
charged to 20 kV only has 20 watt-seconds stored.  Enough\
to blow someone to smithereens (whatever they are), but not
enough to blow up a 10 watt wire wound resistor, provided
the insulation is good enough.  I happen to have a big bank
of 10 k, 10 watt resistors mounted on a circuit board and h ave
never crumped one yet.
