is an electrical component used to store energy in an electric field. It has two electrical conductors separated by a dielectric material that both accumulate charge when connected to a power source. One plate gets a negative charge, and the other gets a positive charge.
A capacitor does not dissipate energy, unlike a resistor. Its capacitance characterizes an ideal capacitor. It is the amount of electric charge on each conductor and the potential difference between them. A capacitor disconnects current in DC and short circuits in AC circuits. The closer the two conductors are and the larger their surface area, the greater its capacitance.
