    How to Identify Series Capacitors?

    A capacitor is composed of two metal electrodes with an insulating dielectric layer between them. When a voltage is applied between two metal electrodes, the energy is stored on the electrodes, so the capacitor is an energy storage element. Any two conductors that are insulated from each other and very close form a capacitor. The parallel plate capacitor is composed of the polar plate and dielectr...
