The secondary KV varies from about 70 KV/inch for small coils to about 10
Kv/inch for large coils. There is a graph in my Tesla Coil Design Manual
showing the Secondary KV/Inch of spark vs the Power Transformer Wattage
(coil size). This graph appears to be the only one ever published and is
based on data from real world coils. The sparks are controlled sparks. The
typical random spark is about two times longer than the controlled spark.

I've been demonstrating my coil for some of my neighbors and inevitably the
question arises of how much voltage is in the leaders beig produced. Is
there a ballpark number per foot? This would sound much more intellignt
than saying "alot".
I've heard that it's around 250KV per foot but I wanted confirmation before
using that number.
