Transformer types — Circuit symbols Transformer with two windings and iron core. Step down or step up transformer. The symbol shows which winding has more turns, but not usually the … Wikipedia
Hartley oscillator — The Hartley oscillator is an LC electronic oscillator that derives its feedback from a tapped coil in parallel with a capacitor (the tank circuit ). Although there is no requirement for there to be mutual coupling between the two coil segments,… … Wikipedia
Transformer — This article is about the electrical device. For the toy line franchise, see Transformers. For other uses, see Transformer (disambiguation). Pole mounted distribution transformer with center tapped secondary winding. This type of transformer is… … Wikipedia
steel — steellike, adj. /steel/, n. 1. any of various modified forms of iron, artificially produced, having a carbon content less than that of pig iron and more than that of wrought iron, and having qualities of hardness, elasticity, and strength varying … Universalium
Center tap — In electronics, a center tap is a connection made to a point half way along a winding of a transformer or inductor, or along the element of a resistor or a potentiometer.Taps are sometimes used on inductors for the coupling of signals, and may… … Wikipedia
Telephone tapping — Wiretap redirects here. For the radio program, see WireTap (radio program). Telephone tapping (also wire tapping or wiretapping in American English) is the monitoring of telephone and Internet conversations by a third party, often by covert means … Wikipedia
Tweeter — A tweeter is a loudspeaker designed to produce high frequencies, typically from around 2,000 hertz to 20,000 hertz (20,000 Hz, generally considered to be the upper limit of the human hearing). A few tweeters can manage response up to an octave or … Wikipedia
Radio transmitter design — In plate modulation systems the voltage delivered to the stage is changed. As the power output available is a function of the supply voltage, the output power is modulated. This can be done using a transformer to alter the anode (plate) voltage.… … Wikipedia
Loudspeaker enclosure — A loudspeaker enclosure is a cabinet designed to transmit sound to the listener via mounted loudspeaker drive units. The major role of the enclosure is to prevent the out of phase sound waves from the rear of the speaker from combining with the… … Wikipedia
Alternating current — (green curve). The horizontal axis measures time; the vertical, current or voltage. In alternating current (AC, also ac) the movement of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge … Wikipedia
Near and far field — This article is about the electromagnetic concept. For the mathematical, see Near field (mathematics). Antenna field regions for antennas that are shorter than the wavelength of the radiation they emit, such as the whip antenna of a citizen s… … Wikipedia
