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.Know More
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 in Electricity
The formula for converting AC voltage to DC is: AC = DC/0.636. The same formula may be used to convert DC voltage into AC voltage.Full Answer >
Resistance in AC and DC currents is the ability of a material, normally a circuit or a resistor, to oppose or restrict the flow of current through it. The amount of resistance that a material gives is referred to as an ohm. Several common materials with high resistance levels include wood, tungsten, air, glass and rubber.Full Answer >
DC current is direct current, which means electricity only flows in one direction; AC current is alternating current, which means it flows in both directions. Batteries run on DC current, while AC current is what comes in through an electrical plug in the wall.Full Answer >
A semi-conductor diode is the most common type of rectifier which converts alternating current, or AC, to direct current, or DC, by allowing only a one-way flow of electrons. The sinusoidal AC input becomes DC voltage output using this process.Full Answer >
