Answer / irfan ahmad

V=440 V
P=30 Kw = 30000 w
we know that ,
P=1.732VI*(power factor)
I=30000/(1.732*440*0.9)
I=43.7 amps [power factor in application is 0.9]

A motor works on 30 killo watts.how much ampers will be required if it works on 440volts?..

Answer / gaurang

We Know the Power Equation

P=1.732*V*I*Cosphi

So As per Details
P=30 KW
V=440 Volts
Then,
I=30 KW/1.732*440*0.8
Wher Cos phi=0.8
I=49 A
