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.

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

Electrical energy is the energy derived from electric potential energy or kinetic energy, associated with the movement of electric charges. It is a versatile form of energy that can be easily converted into other forms such as light, heat, or mechanical energy, making it essential for modern technology and daily life.

Sterilization is a crucial process that eliminates all forms of microbial life, including bacteria, viruses, fungi, and spores, to ensure safety and prevent contamination in medical and laboratory settings. It is achieved through various methods such as heat, chemicals, irradiation, or filtration, each chosen based on the nature of the materials being sterilized and the intended application.
