ball lightning, a rare aerial phenomenon in the form of a luminous sphere that is generally several centimetres in diameter. It usually occurs near the ground during thunderstorms, in close association with cloud-to-ground lightning. It may be red, orange, yellow, white, or blue in colour and is often accompanied by a hissing sound and distinct At 30kV, 1Gohm glass resistance and 10k body resistance - you get only ~3 volts and current is ~3uA. However human is not a resistor, and glass works as capacitor. For high frequency that changes impedance a lot, and glass impedance will be much less for higher frequencies. Plasma balls are often used to provide a “wow” factor that will enthuse students. This article suggests ways in which a plasma ball can be used in lessons and provides some detail about the underlying physics. Stuart Farmer, Robert Gordon’s College, UK With their glowing pink flares and threads of purple lightning, plasma Al Williams. March 1, 2019. You’ve probably seen the videos of a grape — cut almost totally in half — in a microwave creates a plasma. A recent physics paper studies the phenomenon with a I have to directly contradict you here. You are utterly incorrect. They use radio frequency to excite the gas in the ball into a plasma. Kinda like the aurora borealis. The voltage doesn’t need to be high. If it did, then they would not be permitted to sell them to people who were not certified for using high voltage. Not more than a hundred Making a plasma weapon (somewhat) realistic. I want to write a sci fi story where the main weapons in the setting are rayguns that shoot beams of plasma. The gun works by having a magazine filled with gas, a gas chamber, a chamber that energizes the gas and finally a barrel that closes it into a tight beam. I have a few small questions. How does a plasma ball work simple? Basic Operation The plasma ball operates when voltage is introduced in the miniature Tesla coil, creating an electric field inside the ball. As the electrode is negatively charged, the escaping electrons are introduced into the larger glass ball, where they interact with positively charged ions floating Plasma plays a crucial role in the operation and visual effects of plasma ball lamps. It is the fourth state of matter, distinct from solids, liquids, and gases. In a plasma ball lamp, the plasma is created by ionizing a gas mixture inside the glass sphere through the application of a high voltage electric field. A plasma ball is a device that produces arcs of plasma by a large alternating voltage at its centre, creating an electromagnetic field that can light a fluorescent tube.
