mehemayi.
P=V*I
transmitt karana power eka samana wenawa voltiyathawaye saha dharawe gunithayata.
hithanna oya 1kW transfer karanawa kiyala power station eke indala gedarata.
ethakota P niyathayi (1kW)
ehema kalaama V wadi kalot I adu karanna puluwan. V adu kaloth ema power ekama ganna I wadi karannaona.
1kW =230v * 4.34A
1kW = 110V * 9.09A
dan power station eke indala geadarata adina wire eke R kiyala resistance ekak thiyanawa kiyala hithanna. ethakota ema resistance eka nisa waste wena power eka wenne
P(waste) = I*I*R
api hithamu R = 1 ohm kiyala
ethakota 230 yawanawa nam waste eka
P(waste) = 4.34*4.34*1 = 18.83 W
110v use karanawa nam waste eka
P(waste) = 9.09*9.09*1 = 82.62 W
menna me waste eka adu karanna thamayi puluwan tharam wadi voltage transmit karanne. wadi voltage transmit karana eka unsafe but waste eka adui.
thanks a lot අයියේ හොදට පැහැදිලිකරලා දුන්නට....
