IN SINGLE PHASE

POWER= V*I*COS $/1000 KW

IN THREE PHASE

POWER=1.732* V*I*COS $/1000 KW

Answer / rvg

KW = VI Cos $/ 1000

Answer / dnyaneshwar

for single phase
KW= V*I*COS $

FOR THREE PHASE

KW= 1.73*V*I*COS$

IF U HAVE TO FIND ONLY WATTS THEN DIVIDE THE ANS. BY 1000

Answer / manik chatterjee

KW=V*I*COS$ THAT IS INCASE OF AC.
KW=V*I THAT IS IN CASE OF DC.

Answer / manik chatterje

IN CASE OF SINGLE PHASE AC
KW=V*I*COS$
In case of three phase
KW=1.732*V*I*COS$
In case of DC
KW=V*I

Answer / uzair ahmed

To calculate value in KW, just multiply the power with 1000.
becoz unit of power is Watt (W)
so if we convert it to KW then we mutiply it with 1000.
again if we convert KW into Mega Watt. we shall multiply
the value which is in KW to 1000.
and for low values that is maga watt to KW or KW to W, we
shall divide that values with 1000.
