1. The problem statement, all variables and given/known data
I have done a lab consisting of measuring the ion density in a flame plasma (super-hot flame). A "biasing voltage" was applied directly to the flame (via the burner), and I was wondering what is the difference between a non-voltage-biased flame plasma, and a voltage-biased flame plasma.
2. Relevant equations
Plasma physics
positive flame voltage, negative Langmuir probe (sweeping thru flame), positive ions landing on the probe - positive current
3. The attempt at a solution
I am guessing, that the biasing voltage merely boosts the thermal kinetic temperature of the electrons. I don't see how there could be a "resistance" in the plasma.
