Re: Question on Variac lighting

They are a bit brighter, barely perceptable in difference, but a bit
stringy. I like the 1.3 x Cres for the very best spark
appearance. Lots of "hot dancers" off the toroid.

Shouldnt the sparks actually be brighter and thicker, due to
increased amperage in primary & secondary ( when you use too large a
capacitor)?

It also gets heavily into "spark quality" by the viewer. At 1.6 x
Cres (overcapped condition) the sparks will be max but also
"stringy and singular in nature". Right at Cres they will be
multiple and "dance around" a lot. I usually go 1.3 x Cres for a
best compromise. I like to see the sparks dancing around a lot not
just a long single spark off the toroid. Also using a slightly
smaller than "max recommended value" of toroid helps the dancing
effect. It's really up to what you like best.

A question on your point Dr R. If you're overcapped for the
transformer you have, as with the coiler who posted this
question, and there's not enough mA to to charge the cap fast
enough to produce sparks at low variac settings, does this
condition necessarily hinder top end performance? Or does it
just raise the point at which the variac setting initially produces sparks?
In other words, I don't car whether my coil only lights up at 50%
variac or even higher, can I still potentially get near peak
performance with the variac at or near max with an larger than
needed capacitor?
