Nettet18. jun. 2024 · Joule heating, often referred to as Ohmic heating, heats water using electricity by passing electrical current directly through the water. No heating elements are used and, in fact, the equivalent … NettetJoule heating described quantitatively is that the heat evolved per second, or the electric power loss, P, equals the current I squared times the resistance R, or P = I2R. The power P has units of watts, or joules per second, when the current is expressed in amperes …
NettetJoule’s Law of Heating: According to this law, the heat produced in a resistor is directly proportional to the square of current applied to it, directly proportional to the resistance for a given current, and directly proportional to the duration the current is flowing through it. One joule represents (approximately): • The amount of electricity required to run a 1 W device for 1 s. • The energy required to accelerate a 1 kg mass at 1 m/s through a distance of 1 m. • The kinetic energy of a 2 kg mass travelling at 1 m/s, or a 1 kg mass travelling at 1.41 m/s.
