Answer / g.v.suresh kumar

P=VICOS(PIE)
P.F=P/VI
COS(PIE)=REALPOWER/APPARENTPOWER
IT IS LAGGING FOR UNIT(1)

Answer / g.venkat reddy

angle diference between voltage and current,
Pf=truepower/apparent power,(KWH/KVAH),power/voltsxamps,
PF=R/Z

Answer / vishal ingle

we can calculate power factor using formula
P = SQRT(3)* V * I * COS(PHAI)
but for deciding whether leading or lagging p.f we need
complex power
i.e. KVA = KW + j*KVAR or KVA = KW - j*KVAR

Answer / rajkumar

cos(pie)=active power /apparent power..

i.e cos(pie)= KW/KVA
