Can power factor greater than 1?
not possible. power factor is an cosine angle between current and voltage...
When do you use Power Factor?
You use power factor when the load is not resistive, i.e. when it is reactive, and the phase angle between voltage and current is not zero.
What is the power factor in pure inductors explain?
The power factor (cosine of phase angle) of pure inductor is zero because the phase angle between current and voltage is 90 degrees .If the value is substituted in the formula It will be zero.
What is the difference between unity power factor to 8 power factor?
Power factor does not go above 1. It is the cosine of the phase angle between voltage and current and, as such, can range between +1 and -1, although it should be understood that a negative power factor is mathematically equivalent to a generator - when looking at the load as if it is a motor - or vice versa. Unity power factor is applicable for a resistive load. A typical power factor for a big motor is about 0.92. A theoretical power factor of zero, corresponding to a phase angle of 90 degrees, would mean that the load is purely inductive or capacitive, and that the power supply and conductors are also ideal or theoretical.
How do you find whether it is inductor or capacitor if only power factor is given?
in case of inductor or capacitor power factor is always zero.as power factor is cosine of phase angle between voltage and current. in case of inductor and capacitor phase angle between voltage and current is 90 so it become zero so if given power factor is zero then it can be inductor or capacitor.
Why it is power fector of cos?
Power factor is the ratio of the angle between the voltage and current.In the power triangle cosine angle is the ratio between them...
What is the relationship between the firing delay angle and the input power factor?
The firing delay angle is the point in the AC cycle at which a thyristor starts conducting. By adjusting this angle, the power factor of the system can be controlled as it affects the balance between real power and reactive power. A smaller firing delay angle can improve the power factor by reducing the phase difference between voltage and current.

How can you find the power factor?
Power factor is the cosine of the phase angle between voltage and current. It is also KW/KVA.
What is value of power factor?
Power factor value varies from zero to one depending upon the angle between vectorial value of voltage & current and equals to cos fi ( where fi is the angle between i & v)
Of what value is the power factor?
Power factor value varies from zero to one depending upon the angle between vectorial value of voltage & current and equals to cos fi ( where fi is the angle between i & v)
How do convert KVA to KW?
kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.
When do you use Power Factor?
You use power factor when the load is not resistive, i.e. when it is reactive, and the phase angle between voltage and current is not zero.
If we increase the current then what about the power factor?
The power factor depends on the phase angle between the voltage and current on a conductor. The amplitude of the current has no effect on it.
What is the power factor in pure inductors explain?
The power factor (cosine of phase angle) of pure inductor is zero because the phase angle between current and voltage is 90 degrees .If the value is substituted in the formula It will be zero.
What does it mean to have a power factor of 1?
First we need to know what is power factor ? it's cosine of angle between the current and voltage at that point where we wish to measure it. so power factor of "1" means the angle between the voltage and current is 0 degree. It means literally that the current and voltage is in the same phase.
Why is power factor is cos of angle between voltage and current?
Power factor is the ratio of true power to apparent power -if you refer to the so-called 'power triangle', these correspond to the adjacent and hypotenuse of a right-angled triangle. The cosine of the angle between them is the ratio of hypotenuse (apparent power) to adjacent (true power). As the power triangle is derived from the voltage/current phasor diagram, this is exactly the same angle as that between load current and supply voltage.
