A schematic representation of long distance electric power transmission. From left to right: G=generator, U=step-up transformer, V=voltage at beginning of transmission line, Pt=power entering transmission line, I=current in wires, R=total resistance in wires, Pw=power lost in transmission line, Pe=power reaching the end of the transmission line, D=step-down transformer, C=consumers.
Power entry modules frequently allow connections to the equipment circuitry using quick connect tab terminals, also known as blade connectors. An AC inlet connector allows use of a separate, detachable AC line cord that has the type of wall plug favored by the locality. IEC 60320 AC inlet connectors typically used can handle either 120 or 250 ...
Mains electricity or utility power, grid power, domestic power, and wall power, or, in some parts of Canada, hydro, is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electrical grid in many parts of the world.
The portion of instantaneous power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as instantaneous active power, and its time average is known as active power or real power.
The Aug. 15 edition of the Star-Telegram draws our attention to two dozen schools opened with inoperable air conditioners and more than 400 water main breaks in Fort Worth this year. (1A, “Two ...
Higher-frequency AC and transmission lines is somewhat equivalent to sound being transmitted through the water pipes, though this does not properly mirror the cyclical reversal of alternating electric current. As described, the fluid flow conveys pressure fluctuations, but fluids do not reverse at high rates in hydraulic systems, which the ...

AC/DC performed its first show on Dec. 31, 1973, at the Chequers Nightclub in Sydney and has since sold more than 200 million albums worldwide. The group was inducted into the Rock and Roll Hall ...
