Electrical heat generation equation
The most fundamental formula for Joule heating is the generalized power equation: = ) where ... The alternating electrical current coupled with the resistance of the food causes the generation of heat. A higher resistance increases the heat generated. Ohmic heating allows for fast and uniform heating of food … See more Joule heating, also known as resistive, resistance, or Ohmic heating, is the process by which the passage of an electric current through a conductor produces heat. Joule's first law … See more Joule heating is caused by interactions between charge carriers (usually electrons) and the body of the conductor. A potential difference (voltage) between two points of a conductor creates an electric field that accelerates charge carriers in the … See more Overhead power lines transfer electrical energy from electricity producers to consumers. Those power lines have a nonzero resistance … See more Joule-heating or resistive-heating is used in multiple devices and industrial process. The part that converts electricity into heat is called a heating element. Among the many practical uses are: • An incandescent light bulb glows when the filament is heated … See more James Prescott Joule first published in December 1840, an abstract in the Proceedings of the Royal Society, suggesting that heat could be generated by an electrical current. Joule immersed a length of wire in a fixed mass of water and measured the See more Joule heating is referred to as ohmic heating or resistive heating because of its relationship to Ohm's Law. It forms the basis for the large number of practical applications involving See more Direct current The most fundamental formula for Joule heating is the generalized power equation: • $${\displaystyle P}$$ is the power (energy per unit time) … See more
