High voltage — The term high voltage characterizes electrical circuits, in which the voltage used is the cause of particular safety concerns and insulation requirements. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X… … Wikipedia
High-voltage direct current — HVDC or high voltage, direct current electric power transmission systems contrast with the more common alternating current systems as a means for the bulk transmission of electrical power. The modern form of HVDC transmission uses technology… … Wikipedia
Contact electrification — is an obsolete scientific theory from the Enlightenment that attempted to account for all the sources of electric charge known at the time.[1] In the late 18th century, scientists developed sensitive instruments for detecting electrification ,… … Wikipedia
Contact breaker — Breaker arm with contact points at the left. The pivot is on the right and the cam follower is in the middle of the breaker arm. A contact breaker (or points ) is a type of electrical switch, and the term typically refers to the switching device… … Wikipedia
Contact resistance — The term contact resistance refers to the contribution to the total resistance of a material which comes from the electrical leads and connections as opposed to the intrinsic resistance, which is an inherent property, independent of the… … Wikipedia
Contact microphone — Metal disks with piezo material, used in buzzers or as contact microphones A contact microphone, otherwise known as a pickup or a piezo, is a form of microphone designed to sense audio vibrations through solid objects. Unlike normal air… … Wikipedia
Extra-low voltage — IEC voltage range AC DC defining risk High voltage (supply system) > 1000 Vrms > 1500 V electrical arcing Low voltage (supply system) 25–1000 Vrms 60–1500 V electrical shock Extra low voltage (supply system) < 25 V … Wikipedia
Thermal management of high power LED — With the coming of energy saving era, high power light emitting diodes (LEDs) are promising to replace other technologies such as incandescent and fluorescent bulbs in signaling, solid state lighting, and vehicle headlight applications due to… … Wikipedia
Ohmic contact — An ohmic contact is a region on a semiconductor device that has been prepared so that the current voltage (I V) curve of the device is linear and symmetric. If the I V characteristic is non linear and asymmetric, the contact is not ohmic, but is… … Wikipedia
Scanning voltage microscopy — (SVM) sometimes also called nanopotentiometry is a scientific experimental technique based on atomic force microscopy. A conductive probe, usually only a few nanometers wide at the tip, is placed in full contact with an operational electronic or… … Wikipedia
Point-contact transistor — A point contact transistor was the first type of solid state electronic transistor ever constructed. It was made by researchers John Bardeen and Walter Houser Brattain at Bell Laboratories in December of 1947. They were working with physicist… … Wikipedia
