Resistive heating explained in details - EEP

Whenever an electric current flows through a material that has some resistance (i.e., anything but a superconductor), it creates heat. This resistive heating is the result of "friction," as created by microscopic phenomena such as retarding forces and collisions involving the charge carriers

Joule heating - Wikipedia

Joule heating, also known as Ohmic heating and resistive heating, is the process by which the passage of an electric current through a conductor produces heat.. Joule's first law, also known as the Joule–Lenz law, states that the power of heating generated by an electrical conductor is proportional to the product of its resistance and the square of the current:

The Leading Electrical Resistance Heating (ERH) Technology

The natural resistance of the matrix to the flowing electricity gently and uniformly raises the temperature of the treatment volume. It usually takes about 30-45 days to reach steaming temperatures. The elevated temperatures vaporize the VOCs and the steam acts as a carrier gas that transports the vapor phase contaminants to the vadose zone, where TRS captures the vapors and treats them at the surface.
