31Touchscreen — A boy is solving a computerized puzzle using a touchscreen. A touchscreen is an electronic visual display that can detect the presence and location of a touch within the display area. The term generally refers to touching the display of the… …
32Loop antenna — A shortwave loop antenna A loop antenna is a radio antenna consisting of a loop (or loops) of wire, tubing, or other electrical conductor with its ends connected to a balanced transmission line. Within this physical description there are two very …
33Metamaterial — Negative index metamaterial array configuration, which was constructed of copper split ring resonators and wires mounted on interlocking sheets of fiberglass circuit board. The total array consists of 3 by 20×20 unit cells with overall dimensions …
34Common source — Figure 1: Basic N channel JFET common source circuit (neglecting biasing details). Figure 2: Basic N channel JFET common source circuit with source degeneration …
35EIA Class 2 dielectric — The EIA Class 2 dielectric materials are ceramic dielectric materials used in ceramic capacitors. In comparison with the EIA Class 1 dielectrics they tend to have severe temperature drift, high dependence of capacitance on applied voltage, high… …
36Action potential — In physiology, an action potential is a short lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called… …
37Wardenclyffe Tower — (1901 ndash; 1917) also known as the Tesla Tower, was an early wireless telecommunications aerial tower designed by Nikola Tesla and intended for commercial trans Atlantic wireless telephony, broadcasting, and to demonstrate the transmission of… …
38High-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… …
39Valve RF amplifier — A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical , typically (but not exclusively) radio frequency signals.Low to medium power valve amplifiers for frequencies below… …
40Loading coil — In electronics, a loading coil or load coil is a coil (inductor) that does not provide coupling to any other circuit, but is inserted in a circuit to increase its inductance. The need was discovered by Oliver Heaviside in studying the… …
