Joule heating, also known as resistive or ohmic heating, is the process by which the passage of an electric current through a conductor releases heat. This phenomenon is governed by the principle that the energy converted to heat is proportional to the square of the current, the resistance of the conductor, and the time the current flows, as described by the formula P = I^2R.

Joule heating

Resistive heating, also known as Joule heating, occurs when an electric current passes through a conductor, converting electrical energy into heat due to the resistance of the material. This principle is widely used in applications like electric heaters, toasters, and incandescent light bulbs, where heat generation is desired for functionality.

Resistive Heating

Ohmic heating, also known as Joule heating, is the process of converting electrical energy into heat energy by passing an electric current through a conductor. This phenomenon is widely utilized in various applications, including food processing and sterilization, due to its ability to uniformly heat materials with high efficiency.
