What is an electric arc?
The electric arc is the flow of the electric current present between the two electrodes that are formed when electricity jumps from one electrode to another. The connection made from the jump creates a "bridge" or an arch visible to the eye. The electric arch contains extremely high heat and brightness, ideal for welding and lighting.
The temperature and clarity of electrical arches usually depend on two factors: type of gas and pressure. When the electric current travels in the gap between the electrodes, the air warms up around it. Changing the chemical composition of the air can be changed and the electrical arc brightness. Air can be removed to create a vacuum or gas can be added to form high -pressure arches. Both are used in different types of lighting.
The coil is a type of electric noise that works in regular atmospheric pressure. His inventor, Nikola Tesla, is generally considered to be the forerunner of the image of a "mad scientist". This picture was conjured when the pictures showed him that PThey equal experiments under the light of electrical arches working in the background.
Lightning is a naturally occurring electric arc that provides the same spectacle. Electricity created in the air travels to the ground or other clouds. It forms an electric arc flash that can reach several yards (meters) long.
Electric arc furnace use high heat in the arch to melt metals. Electricity passes through metals, which warms them to the melting point. Using this method, metals of scrap are commonly melted. The energy from the furnace is usually lower compared to the blast furnace. The ability to stop quickly and trigger the arc furnace allows the award mill to change the load on its needs.
The direction uses the same principle for welding an electric arch. The metal bars are electrified by the power supply and an electric arc is formed when you contact another metal. Ample heat is formedRO melting two metals. Electric arc welders then use this process to weld two metals together.
One interesting use for an electric arch is on plasma speakers. Instead of using traditional speakers to produce sound, most plasma speakers use ionized gas or live electricity. The expansion and contraction of the arc, when the current passes through it, disrupts the air. It produces the sound again. It is said that plasma speakers create a brighter sound by not having a physical restriction that has many other speakers.
