Answer / guest

phase difference between voltage and current

Answer / soumen

pf is cosine angle between voltage &current. .I.e pf=vicoso

Answer / ankit

Power factor is masure of ability to how much apprent power is used as active power by any load.

Answer / guest

power factor is the same as slip in induction motor that the difference b/w stetor speed(supplied speed ie N S) and rotor speed (used speed) upon stetor speed * 100 and incase of power distribution pf = used power for a particular load(loads) /supplied power for that particular load(loads) ie kw/kva and etc. I wellcome any suggestion regarding this.
