My question is, What was the function of a capacitor in an electric current?

Could someone please help me I ruled out one of my theorys already and that was to increase circuit power.

Was it to allow current flow between its plates?
Was it to measure the amount of current in the curcuit?
or Was it to store electric currents?

What? this website says its an expired webpage.

The function of a capacitor in an electric current is to store electric charge. It does not increase circuit power or measure the amount of current in the circuit.

To understand this concept, think of a capacitor as a temporary reservoir for electric charge. It consists of two conductive plates separated by an insulating material called a dielectric. When a voltage is applied across the capacitor, one plate accumulates positive charge while the other plate accumulates negative charge. This creates an electric field between the plates.

The capacitor stores energy in its electric field, similar to how a battery stores energy in a chemical form. As a result, when the circuit is connected to a power source, the capacitor charges up by accumulating and storing electric charge on its plates. When the power source is disconnected, the stored charge can be released back into the circuit, providing a temporary burst of electrical energy.

So, to answer your question, the function of a capacitor in an electric current is to store electric charge, not to allow current flow between its plates or measure the amount of current in the circuit.
