I do not want to get to scientific, but more on electric technical side. Does it conduct at certain voltage (short). Why do some have resistors (To limit current?)?

I have recently experimented with one and applied 120VAC only to one side without completing the "loop"; The bulb was "dim".A neon bulb does not conduct at all, up to a certain voltage. Then the gas in the tube ionizes and it starts conducting. At that point, it pretty much looks like a short circuit, so the current must be limited by a resistor or it will blow up. Once the gas is ionized, it will conduct at a lower voltage than was initially needed. This is called negative resistance, since an increase in current was accompanied by a decrease in voltage across the bulb.

What was the other side connected to?I have recently experimented with one and applied 120VAC only to one side without completing the "loop"; The bulb was "dim".
The loop was completed, by leakage current through its surroundings.without completing the "loop"
No where (floating).What was the other side connected to?
This is what I figured.The loop was completed, by leakage current through its surroundings.
One year people in one of my electronics labs entertained themselves by holding a neon bulb and inserting the other lead in a wall socket and watching them glow.This is what I figured.
Basically the way that Neon AC power detection screwdrivers work.One year people in one of my electronics labs entertained themselves by holding a neon bulb and inserting the other lead in a wall socket and watching them glow.
What colour did those lab people glow?One year people in one of my electronics labs entertained themselves by holding a neon bulb and inserting the other lead in a wall socket and watching them glow.
