In electric power distribution, capacitors are used for power factor correction. Such capacitors often come as three capacitors connected as a three-phase Electrical load. Usually, the values of these capacitors are given not in farads but rather as a reactive power in volt-amperes reactive (VAr). The purpose is to counteract inductive loading from devices like Induction motors, electric motors and transmission lines to make the load appear primarily resistive. Individual motor or la…

When using capacitors in power jumper circuits to eliminate noise, not just normal voltages, but also the generation of abnormal pulse voltages (such as lightning) must be taken into account, which may cause the …
In most systems, capacitors are placed throughout a design to ensure there are no voltage drops on the supply rails. When power is initially applied to the system, charging these capacitors can result in an inrush current which can exceed the nominal load current. If left unaddressed, this can cause voltage rails
A capacitor is a passive component, so it can''t amplify. Full stop. That text isn''t good. What it probably meant to say is that, using capacitors, you can build frequency-selective circuits (for example, an R-C low pass filter). And what it meant to say was maybe that Opamps can be used in configurations that are not frequency-selective (within the limits of the opamp).
Popping capacitors across a brushed motor reduces noise from the motor, but to a fast PWM edge, those lovely capacitors can be a horrible load, so you should add some inductance into the PWM output stage to make the load more palatable. Also note that an X2Y capacitor makes use of the motor case as its ground - but that in turns means the case ...
