PIRA 5B30.10 - Plasma Light

• Turn on the Plasma ball.
  


• Turn off the lights in the room for better visibility.
  


• Place your fingers on the ball and watch what happens.
  


• If desired, request for a stool to stand on to insulate the human body from ground.
  

Concept Conveyed:

• Lamp is filled with noble gases and one electrode placed at the center.


• The colors observed are due to neon, argon, and xenon gases.


• When touching the plasma ball, the electrons will go through the human body to the ground.


• May also convey an AC circuit as the glass (insulator) acts as a dielectric in a capacitor while the human body touching the glass, as well as the electrode inside, acts as conductors. The power supply (connecting the plasma light to Earth) is AC.
