if we convert ampers into kw,which one formula use by us,pls tell me?..

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

if we convert ampers into kw,which one formula use by us,pls tell me?..

Answer / pillay

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

if we convert ampers into kw,which one formula use by us,pls tell me?..

Answer / arockia doss

Power(KW)*1000 = 1.732*V*I*Cos(pi)

I = KW*1000 /(1.732*V*Cos(pi))

if we convert ampers into kw,which one formula use by us,pls tell me?..

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
