1. Relating to both electricity and heat, particularly to heat produced by electrical current.
2. A reference to an electric blanket containing resistance heaters for heating tissue and relieving pain.
3. A reference to both heat and electricity; in particular, pertaining to the conversion of electrical energy into heat energy.
4. The heating effect of electric current, or the electric current produced by heat.

An ammeter (device for measuring an electric current in amperes) that is actuated by the voltage generated in a thermocouple through which it receives the current to be measured.

It is used primarily for measuring radio-frequency currents.

1. A process in which electrical energy is directly converted into heat energy.
2. The direct conversion of electric energy into heat energy, as in an electric heater.

An actuating element consisting of a wire strip or other shape and having a high coefficient of thermal expansion.

An apparatus which depends for its operation on the heating effect of an electric current.

1. A process in which an electric current is used to produce heat.
2. Used to generate higher temperatures than can be produced by combustion processes.
3. Any process that uses an electric current to generate heat, utilizing resistance, arcs, or induction.

It is used to achieve temperatures higher than those which can be obtained by combustion methods.

1. A type of rocket propulsion in which the propellant is heated electrically; such as, an electric arc that is used to heat hydrogen gas in an arc-jet engine.
2. The propulsion of spacecraft by using an electric arc or other electric heater to bring hydrogen gas or other propellant to the high temperature required for maximum thrust; for example, an arc-jet engine.
3. Vehicular propulsion which involves electrical heating to raise the energy level of the propellant.

In contrast, chemical rockets use the chemical energy of one or more propellants to heat and to accelerate the decomposition products (monopropellants) or combustion products (bipropellants) for thrusting purposes.

In both instances, the high-energy propellant gases are exhausted through a nozzle where they are accelerated to a high velocity, and thrust is produced by reaction.

A recorder in which heat produces an image on the recording medium in response to the received signals.

1. In facsimile (fax) or an instrument that transmits and reproduces documents with digitized signals which are sent over telephone lines, a technique in which an image is produced on a recording medium by heat generated by electronic signals.
2. A type of electrochemical recording, used in facsimile equipment, in which the chemical change is produced principally by signal-controlled thermal action.

1. An electrothermal ammeter (instrument for measuring an electric current in amperes or basic units of electric current) employing a series resistor as a multiplier, and so measuring voltage instead of current.
2. An instrument which measures voltage and operates as an electrothermal ammeter, using a series resistor as a multiplier.
