Induction motors,otors running from the 240V supply are among the commonest in domestic use. All induction motors are cheap, reliable, rugged, lightweight and reasonably efficient; in fact large (> 1 MW) induction motors have efficiencies of up to 98%. Their biggest drawback hitherto has been their small range of op

Johanna Alkan Olsson,Lotta Anderssonnts. However, nearly all electricity is generated and consumed in the form of AC. In order to continue to use the methods devised originally for DC circuits, Heaviside. developed the use of complex numbers for currents, voltages and impedances. This has proved to be the most powerful tool ever put i
