The cosine of the angle between voltage and current in an a.c circuit is called as power factor(pf).

CosØ= R/Z
CosØ= Apparent Power / Active Power

Answer / abhishek

power factor tell us by which ratio the output wave of any load differs from the output wave of resistive load. 

Answer / ashok

1. The cosine angle between voltage and current in a AC circuit is called PF.
POWER FACTOR=P/VI
POWER FACTOR=KW/KVA
2. The ratio between resistance and impedance
POWER FACTOR=R/Z

what is the exact direction of current? as we know current travels from higher potential to lower potential,so if we take battery +ve to -ve implies current direction is from positive terminal to negative terminal.,whereas electrons flow from negative to positive as they are attracted by positive ions.current will be the plow of charge but not flow of positive ions.please clarify my doubt friends.
