Thyratron
A gas-filled triode tube commonly employed in electronic timers and phototimers.
-
Thumb rule
If the wire or conductor is held in the left hand, with the thumb pointing in the direction of the electron flow (from negative to positive), the encircling fingers will indicate the direction of the magnetic field lines around the electron flow.
-
Three-phase generator
A generator powered by three single-phase currents that are deliberately out of phase with each other by one-third of a cycle or 120 degrees.

Thoriated tungsten filament
A vacuum tube filament, typically composed of tungsten blended with a small amount of thorium oxide, is employed to enhance electron efficiency.
-
Thoramat
The Siemens fully automated setup designed for diagnostic chest imaging incorporates a film magazine with a cutting mechanism, along with an integrated processing machine.
-
Thoraeus filter
An essential radiological filter consisting of tin is employed as the primary filter, complemented by a secondary filter composed of copper to absorb the characteristic radiation emitted by the tin. Furthermore, a third filter made of aluminum is utilized to absorb the characteristic radiation produced by the copper. In the kilovolt range of 200 to…

Thermoelectron
Electrons are released through the process of heating a metal filament, which serves as the filament within an x-ray tube.
-
Thermionic vacuum tube
Any electronic tube equipped with a filament exhibits the ability to emit electrons upon heating. Examples of such tubes include x-ray tubes, valve tubes, photo tubes, and various others.

Thermal radiation
Heat radiation, a phenomenon observed in all objects with a temperature above absolute zero, manifests as thermal energy emission. This radiant energy encompasses a range of wavelengths, spanning from the briefest ultraviolet rays, through the spectrum of visible light, to the most extended infrared wavelengths. It is commonly referred to as heat due to its…
