The Australian rock band AC/DC chose their name based on the acronym's representation of the two forms of electrical power, alternating current (AC) and direct current (DC), which symbolized the band's high-powered approach to their performances. Accordingly, the band's logo, designed in 1977, consists of the two electrical terms separated by a lightning bolt. The band's founding members, guitarists and brothers Angus and Malcolm Young, have said that the idea for the band name came to them after their sister, Margaret Young, spotted the acronym on a sewing machine.Continue Reading
AC/DC was formed in November 1973 and the band released its first album, "High Voltage," in February of 1975. They have since become one of the highest-grossing bands in the history of rock music. The band recovered from the death of lead singer Bon Scott in 1980 by hiring replacement singer Brian Johnson. The album that was released later that same year, "Back in Black," became a best-seller with more than 10,000 copies sold each day during its first week of release.
The band's signature sound is based on a double-guitar format driven by loud, pounding, riff-oriented guitar lines. Malcolm Young handles the rhythm guitar parts while brother, Angus, dressed in the schoolboy uniform stage attire suggested by sister Margaret, plays lead guitar. Angus' characteristic guitar solos and stage persona, coupled with his brother's solid power-chord approach to rhythm, accounts for a major portion of the band's appeal.Learn more about Electricity
An alternating current (AC) adapter converts AC power into direct current (DC) power to charge or power small electronic devices. AC adapters convert and transfer voltage from electrical outlets to power everyday devices such as laptops, mobile gaming devices and cellphones.Full Answer >
A half wave rectifier is a type of circuit that is used to convert alternating current (AC) power into direct current (DC) power. It gets its name from the fact that only half the sine wave of the AC current passes through it and is converted to DC.Full Answer >

Wind power harnesses the movement of the wind to turn electrical turbines, generating power. Large windmill-like turbines with canted blades catch the wind, rotating around a central axle. This axle connects to the central rotor of an electric turbine. As the turbine spins, the interaction of copper wires and magnets creates an electrical current.Full Answer >
