N=3L(L-1)+1 Where N=No of strand L=No of layer of cable. ie A single layer(single strand) N=3*1(1-1)+1=1 A double layer cable N=3*2(2-1)+1=7 And in three layer cable N=3*3(3-1)+1=19 And . so on ........ But Now-a-days some manufacuture company does not supply the exact size (No of strand) of cable for economic benefit.

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. ? Output Power for these Appliances Would be same like this : P = V * A * P.F Or would be changed ? thanks
