Answer / rangnath
For AC Circuit,
KW = (V*I*PF)/ 1000
And For DC Circuit,
KW = (V*I)/ 1000
Where V = Voltage, I = Current, and PF = Power Factor

there is no one formula only.
there are some formulas that you must know,,
you must know how to use the correct one when you need it.
for DC power it is always just voltage x current = watts
for AC single phase it is always volt x current x pf = watts
for AC 3 phase it is root 3 x volt x current x pf = watts
the watts than you change to KW or MW if necessary.
this are all for real calculations. when you practice with it often than you will be able to give an estimate bcos the pf varies according to situation.

Answer / kumavat nareshkumar .c.
kw=v*i*cos(phi)/1000 in 1-phase ac
kw=1.73*v*i*cos(phi)/1000 in 3-phase ac
kw=v*i/1000 in dc

Answer / kumavat nareshkumar .c.
kw=v*i*cos(phi)*1000 in ac
kw=v*i*1000 in dc
where v=voltage,i=current,cos(phi)=powerfactor

Answer / arockia doss
Power(KW)*1000 = 1.732*V*I*Cos(pi)
I = KW*1000 /(1.732*V*Cos(pi))

Answer / dinesh (techie.dinesh@gmail.co
first, KVA*PF=KW
WE know that, power = VI
so KW=VI
KVA*PF=VI
so, I= (KVA*PF)/ V

Answer / sud
WE CANNOT CONVERT AMPERS INTO kw we can only convert amps
into kiloamps or watts into kilowatts, h.p
