Various semiconductor diodes. Left: A four-diode bridge rectifier.Next to it is a 1N4148 signal diode.On the far right is a Zener diode.In most diodes, a white or black painted band identifies the cathode into which electrons will flow when the diode is conducting.

If the semiconductor is translucent, the junction becomes the source of light, thus becoming a light-emitting diode. I-V diagram for a diode. An LED begins to emit light when more than 2 or 3 volts is applied in the forward direction.
Zener diodes have a low breakdown voltage. A standard value for breakdown voltage is for instance 5.6 V. This means that the voltage at the cathode cannot be more than about 5.6 V higher than the voltage at the anode (though there is a slight rise with current), because the diode breaks down, and therefore conducts, if the voltage gets any higher.
A tow hitch (or tow bar or trailer hitch in North America [1]) is a device attached to the chassis of a vehicle for towing, or a towbar to an aircraft nose gear. It can take the form of a tow ball to allow swiveling and articulation of a trailer , or a tow pin, or a tow hook with a trailer loop, often used for large or agricultural vehicles ...
Diagram of a high-pressure sodium lamp A high-pressure sodium lamp, Philips Master SDW-T 100W. Various types of chemistry are used in the arc tubes of HID lamps, depending on the desired characteristics of light intensity, correlated color temperature, color rendering index (CRI), energy efficiency, and lifespan.
Intelligent Light System is a headlamp beam control system introduced in 2006 on the Mercedes-Benz E-Class (W211) [154] which offers five different bi-xenon light functions, [155] each of which is suited to typical driving or weather conditions: Country mode; Motorway mode; Enhanced fog lamps; Active light function (Advanced front-lighting ...
The first electric-powered torque amplifier was invented in 1925 by Henry W. Nieman of the Bethlehem Steel Company of Bethlehem, Pennsylvania. [1] It was intended to allow manual control of heavy equipment; e.g., industrial cranes, artillery, etc. Vannevar Bush used Nieman's torque amplifier as part of his differential analyzer project at M.I.T in the early 1930s.
