What Is a Capacitor and What Is It Used For? - MUO
2022年5月18日 · Capacitors (originally called electrical condensers) are analog electrical components that can collect and store electrical energy. As a direct current flows into a capacitor, it charges with energy and releases an alternating current flow back into the circuit.
Capacitor - Wikipedia
Capacitors are widely used as parts of electrical circuits in many common electrical devices. Unlike a resistor, an ideal capacitor does not dissipate energy, although real-life capacitors do dissipate a small amount (see Non-ideal behavior).
Capacitor in Electronics – What It Is and What It Does
2024年5月19日 · Capacitors store energy in an electric field and release energy very quickly. They are useful in applications requiring rapid charge and discharge cycles. Batteries store energy chemically and release it more slowly. They are useful for providing a steady supply of energy over a longer period.
