**1).**The Cosine of angle between Current and Voltage is called Power Factor.

P = VI Cosθ OR

Cosθ = P / V I OR

Cosθ = kW / kVA

Cosθ = True Power/ Apparent Power

**2).**The ratio between resistance and Impedance is Called Power Factor.

Cosθ = R/Z

**3).**The ratio between Actual Power and Apparent Power is called power factor.

Cosθ = kW / kVA

Simple and easy to understand, thanks

Welcome 🙂

That’s easy to understand!

Now, what analogy can be given to a capacitor to show that even a capacitor is involved in the concept of Power Factor? It will give an even more clear understanding!

You may check the links at the end of the above post 🙂

sir i want to save it..how it is possible?<br />easy to perceive,nice way to demonstrate.thanks

i too expected same example from you<br />

I want to download free e-books. so plz invite me to do so.

the total power factor in actual is a product of the displacement power factor(cos[fi]) and the distortion power factor.the distortion power factor is a function of the total harmonic distortion,hence the total power factor of the system decreases on in actual practice on account of the presence of harmonics and other non linearities.

REALY GOOD EXPLICATION…Thanks!!<br />

its banificial for us that’s why thanks

sir plz upload 3 phase transformer 25 kva step down oil immresd self cooled core and winding calculation.

sir plz answer the question its about control i know you can answer it …. which transform we use for convergence ? Laplace transform or Fourier transform or Z transform

Its very simple to understand.I never understand about these three power concept.

Thanks sir.
