valokaaresta
Valokaari, also known as an electric arc, is a sustained electrical discharge through a gas that produces light and heat. It occurs when a sufficiently high voltage is applied across two electrodes separated by a gas, causing the gas to ionize and become conductive. This ionization creates a plasma, a state of matter composed of ions and electrons, which glows brightly.
Valokaari has been utilized in various applications throughout history. One of the earliest uses was in arc
The characteristics of a valokaari, such as its voltage, current, and temperature, depend on factors like electrode
