what is meant by lagging and leading current in ac circuit
Leading and lagging current Leading and lagging current are phenomena that occur as a result of alternating current. In a circuit with alternating current, the value of voltage and current vary sinusoidally. In these types of circuits, the terms lead, lag, or in phase are used to describe current with reference to voltage. Current is in phase with voltage when there is no phase shift between the sinusoids describing their time varying behavior. This generally occurs when the load drawing the current is resistive.
AC/DC Malcolm and Angus Young developed the idea for the band's name after their sister, Margaret Young, saw the initials "AC/DC" on a sewing machine. "AC/DC" is an abbreviation meaning "alternating current/direct current" electricity. The brothers felt that this name symbolised the band's raw energy, power-driven performances of their music.[23][24] "AC/DC" is pronounced one letter at a time, though the band are colloquially known as "Acca Dacca" in Australia.[25][26] The AC/DC band name is stylised with a high voltage sign separating the "AC" and "DC" and has been used on all studio albums, with the exception of the international version of Dirty Deeds Done Dirt Cheap.[27]
