for generators it is taken as 1.5 A/sq mm.For duration of
less than 4 hours 6A/sq mm

Answer / shahzad

current density =current/area
as the current density for copper is normaly 3 so
3=current/.75
current=3*.75=2.25A

Which are resistive loads & which one are inductive loads : Refrigerator, Split air conditioner, ceiling fans, well pump, fluoresecent bulbs, T.V, CRT Monitors, Adsl Routers, C.P.U, Printers, Deep Freezers, Speakers, DVD Players, Microwave oven etc. ?
