Electric Arc (Noun)
Meaning
Electrical conduction through a gas in an applied electric field.
Classification
Nouns denoting natural phenomena.
Examples
- An electric arc is a continuous discharge of electricity through a gas, often producing a bright path of ionized gas and light.
- In an electric arc, the high voltage applied across a gap in a gas creates a conductive plasma arc, which is sustained by the flow of electrical current.
- When a high voltage is applied across a small gap in a gas-filled chamber, an electric arc forms due to the breakdown of the gas molecules and the conduction of electricity through the resulting plasma.
- The electric arc furnace uses an electric arc to melt and refine metals, with the arc being sustained by the electrical current flowing through the ionized gas.
- In welding processes, an electric arc is created between the metal workpiece and an electrode, producing a high-temperature plasma that melts and joins the metal surfaces together.
