Answer / abo ibrahim
Active Power=1.732*Load Current*Line Voltage*P.F.
P.F=0.8.
Active Power= 30kw = 3o*1000= 30000w
Load Current= 30000\(1.732*440*0.8).
=49.21 Amp.

Answer / pinoy
P=1.732 X LINE VOLTGE X I ; NO NEED TO MULTIPLY BY P.F
SINCE POWER (KW) IS KNOWN HENCE,ONLY MULTIPLY BY P.F IF
P=KVA
I=30KW/1.732(440)
=39.37AMPERES,
