The second use of capacitors is for use in certain types of single phase motors. These have two separate windings and by putting a suitable capacitor across the ''input'' side of both, the addition of a live feed to one side of the capacitor or
Batteries are like capacitors? : r/ElectricalEngineering
Batteries aren''t really like capacitors at all aside from the fact that they can store energy. Capacitors are not used for energy storage they same way that batteries are (aside from super capacitors maybe), instead they can be thought of as buckets that can store small amounts (compared to a battery) of energy to supply extra current when switching on a chip occurs (i.e

What happens when a capacitor is connected to a power source?
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
How does a capacitor work?
The capacitor charges and discharges cyclically. This results in an AC current flowing through the capacitor, with the capacitor acting as a reactive component that impedes the flow of AC to a degree that depends on the frequency of the AC signal. The concept of the capacitor dates back to the 18th century.
How much electricity can a capacitor store?
The amount of electrical energy a capacitor can store depends on its capacitance. The capacitance of a capacitor is a bit like the size of a bucket: the bigger the bucket, the more water it can store; the bigger the capacitance, the more electricity a capacitor can store. There are three ways to increase the capacitance of a capacitor.
