Ohmic heating, also known as Joule and resistive heating, is a process whereby electric current is passed directly through an item in order to heat it.

It is suitable for materials that are reasonably good conductors and often difficult to treat (because they are heat-sensitive, very viscous or messy, for instance). It can quickly heat large volumes at very precise power levels.
