I don't think it is as simple as that. What you have is a "plasma ball" 
with a nice prickly central electrode. If Tesla could see streamers rising 
from grounded objects it can happen in this situation as well and 
contribute to coil heating
In addition if you feed the coil RF hash it may resonate.  I have seen this 
oscillation of a light globe discussed before but this is the only article 
I could google at present
