From a technical point of view, it doesn't really matter, as long as it's in parallel with the load. In practise, there are different approaches. Individual loads can have capacitors connected across their terminals, or they can be connected at the point of entry of the supply.

What happens to an inductive circuit when capacitance is added for power factor correction?
The capacitance counter acts the inductivity (decreases it) without impacting the resistivivity, thus increasing the power factor, or resistivity / inductivity ratio.
What can be done to improve the power factor?
Power factor is the percentage of actual useful energy obtained from an electrical device as opposed to the wasted energy lost to impedience of a circuit. ie heat, voltage drop. Improvement is to raise this percentage to as close to 100% as possible.
What is the use of synchronous machines in power grid system?
To improve the power factor
Why inductor is used in electrical circuit?
To improve the power factor
How is power factor improved in fluorescent lamps?
the old ones with transformers you can correct with capacitors incandescent lamps have unity power factor the newer florescent ballasts are closer to unity but tend more towards capacitance

Power factor is least in capacitance or resistance or inductance?
inductance

How power factor helps to improve circuit?
Improving power factor does nothing to improve a circuit. It merely affects the amount of current drawn by the load.
Why the power factor improves with the load?
Power factor doesn't necessarily 'improve with the load', but it is determined by the load.
Why does a capacitor improve power factor?
yes power capacitar ust inprove the power factor and sae the kvah reding
What will b the power factor of a series circut when r is made zero?
The power factor never depends on the resistance of a circuit. It depends on the equivalent inductance and capacitance in the circuit, and on the frequency of the power supply, even if the resistance is zero.
What is the technique of improve the power factor?
Simple technique by adding PP capacitor with automatic power factor controller.
What is the use of synchronous machines in power grid system?
To improve the power factor
What is the Relationship between power factor and current?
When voltage and current waveforms are out of synch the power factor is reduced. In a pure resistance load the PF is 1. When inductance and capacitance is involved the PF is from 0 to 1.
How do you build a capacitor bank to maximize electrical power?
capacitor bank make in delta connectionIf you are asking about improving the power factor to decrease the surcharge you pay for having a low power factor you have to go about it like this.Check your utility bill to find out what your existing power factor reading is. Power factor is the measure of how effectively your equipment converts electric current into useful power output.The ratio of your usable power consumption in kilowatts to your reactive power consumption in kilo-vars determine your power factor.When your power factor drops below 90%, a power factor surcharge is applied to cover the cost of supplying additional reactive power.This usually applies to industrial and commercial buildings that have large and many motor loads. Inductive reactance from motors can be opposed by capacitive reactance. Adding capacitors to the system will improve your power factor which will bring your reading up to over 90%.There are charts available where you can graph your existing reading and what you want to improve the power factor to. In the capacitor scale you are told how much capacitance has to be added to the system to get you to the higher reading.On very large motors capacitors are added on the load side of the magnetic contactor so that when the motor is in operation the capacitors are in the motor circuit and when the motor's magnetic contactor drops out the capacitors also drop out of the circuit.For chart see related links below
Can the capacitor be inserted in series in order to improve the power factor?
In a circut we use capacitor in series for improving power factor
