Electric field across capacitor

WebApr 14, 2024 · ε 0 is the permittivity of vacuum. ε r is the relative permittivity of the material. A is the area of the plates. d is the distance between the plates. C is the capacitance in … WebHowever, the electric field between the plates remains strong, and the capacitor stores the electrical energy. When the voltage source is disconnected from the circuit, the capacitor begins to discharge. As the capacitor discharges, the voltage across its plates decreases, and the electric field between the plates weakens.
