A capacitor in parallell to the motor. This should be as close as possible to the load. Is used on such things as motors.

It all depends on why and where you are doing it.
On power transmission lines, they use HUGE capacitors every now and then to cancel out the inductance of the transmission line itself.
The capacitor on the motor is used for entirely different purpose if you are looking at a single phase motor.
In most industrial and home usages, loads are inductive. (ie. motor) There aren't that many capacitive loads. In that sense, capacitors are used for power factor corrections.
If you are to expand this and say in general circuits, if you want to compensate for voltage lag current, or current lag voltage situations, (which creates the power factor in the first place), then you use the opposit. Capacitive loads use inductors. Inductive loads use capacitors.

all of it relies upon upon why and the place you're doing it. On energy transmission lines, they use substantial capacitors now and returned to cancel out the inductance of the transmission line itself. The capacitor on the motor is used for completely distinctive reason in case you're watching a single section motor. In maximum commercial and abode usages, plenty are inductive. (ie. Motor) There are not that many capacitive hundreds. In that experience, capacitors are used for vigor factor corrections. once you're to boost this and say often circuits, in case you want to seize up on voltage lag present day, or present day lag voltage circumstances, (which creates the skill ingredient interior the 1st project), then you definately use the opposit. Capacitive hundreds use inductors. Inductive plenty use capacitors.

If the circuit is an inductive one, you have to use capacitors.
If the circuit is capacitive, you hve to use inductance.
The most widely found situations are inductive circuits caused by motors etc.

There are capacitors made for that. They are often used with large motors to cancel out the inductive effect of the motor coils.

Question is not clear... sounds like you need a resistor - since they drop energy as heat - but value depends on current, voltage etc...

You use a bank of capacitors......
