Galvanothermometer

Example:The galvanothermometer uses the flow of electricity to measure temperature changes.

Definition:The flow of charged particles, such as electrons, through a conductor, accompanied by the changes in electrical potential such as those produced in a galvanothermometer.

Example:Galvanothermometers rely on the thermoelectric effect to measure temperature differences.

Definition:A physical phenomenon in which the thermopower (the voltage difference between two different metals or alloys at different temperatures) produces a measurable voltage.

Example:Galvanothermometers often use thermocouples to generate the necessary voltage.

Definition:A temperature-measuring device consisting of two different metals or alloys joined together at one end and connected to a measuring instrument.
