A large, charged capacitor, such as those found in flash units and TVs, can be extremely dangerous and can, potentially, kill you with the charge they contain.
It's impractical to use capacitors to store any significant amount of power unless you do it at a high voltage. The difference between a capacitor and a battery is that a capacitor can dump its entire charge in a tiny fraction of a second, where a battery would take minutes to completely discharge.
When discussing how a capacitor works in a DC circuit, you either focus on the steady state scenarios or look at the changes in regards to time. However, with an AC circuit, you generally look at the response of a circuit in regards to the frequency. This is because a capacitor's impedance isn't set - it's dependent on the frequency.
There's almost no circuit which doesn't have a capacitor on it, and along with resistors and inductors, they are the basic passive components that we use in electronics. What is Capacitor? A capacitor is a device capable of storing energy in a form of an electric charge.
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.
Potential Difference Maintained: The capacitor maintains a potential difference across its plates equal to the voltage of the power source. This potential difference is accessible when the capacitor is connected to another circuit element.
