Plasma Arch

A plasma arch is a phenomenon where ionized gas, or plasma, forms a visible arc between two electrodes. This occurs when a large voltage is applied, causing air or another gas to become conductive. The resulting arc can glow brightly and may produce heat, light, and sound, similar to lightning. Plasma arches are used in various applications, including welding, lighting, and experiments in physics. They are fascinating because they demonstrate the behavior of electricity in gases and the potential of plasma, which is a state of matter distinct from solids, liquids, and traditional gases.
