Power factor is well defined and measures the difference between the phase of current and voltage. It varies from 1 to zero with 1 being associated with a pure resistive load. Since you multiply voltage times current to compute instantaneous power; if they are out of phase then you get reduced power. A power booster, in this context, would be a device that was designed to compensate for the our of phase situation and bring the phases more in line, effectively boosting power.

What is the difference between a brake booster and power brakes?
The brake booster is part of the power brake system.
What does difference between Watt and Volt ampare?
No difference in case of DC. In case of AC Watt refers to Power which includes the factor of power factor. VA does not include power factor.
What is the difference between an amplifier and a booster?
an amplifier is electronic equipment that increases strength of a signal and a booster is voltage regulation in (DC) direct current electrical power circuits. Basically an amplifier increases strength and a booster regulates voltage.
What does power factor mean in math?
power factor is the cosine of the angular difference between current and voltage and must be taken into account to get true power (watts)
What is difference between 0.8 leading and 0.8 lagging power factors?
Power factor measures the phase difference between voltage and current. If they are in phase the Power Factor is one. If the current and voltage are out of phase the power factor is between zero and one. You can describe the PF by saying the current lags the voltage with a PF = .8 or the voltage leads the current with a .8 PF.
Is a power booster and a brake booster the same?
I would say a power brake booster or a brake booster would be the same.
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.
How does reactive power change the Power Factor?
Power Factor is the relationship between the phase of the current and voltage which are each sine waves. When there is an inductance in a circuit the AC current waveform tends to lag the voltage. This causes a phase difference which reduces the Power Factor from a maximum of one to something less.
Why is the power factor at no load less than full load?
That's not possible. The power factor is related to the phase difference between voltage and current on the line. "No load" means 'no current', so power factor is meaningless with no load. If you see a power factor, there must be a load, even if it's some device that you're not aware of.
What is the difference between Era liquid laundry detergent and Era with Oxi Booster laundry detergent?
Both are excellent products and will be able to provide whatever service you request of them. The difference with is the Era Oxi Booster has higher levels of cleaning agents than the Era liquid and therefore gives you overall better cleaning power.
Introduction to power and power factor?
The power is the product between the magnitude of voltage and the magnitude of current. Whereas the power factor is a ratio between the active power and the apparent power.
