• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
The capacitance 'C' is defined as the charge (Q) stored per unit potential difference (V), i.e., C = Q/V. For a parallel plate capacitor, Q = σA, where 'A' is the area of one plate. 5. Substituting Q = σA and V = σd/ϵ₀ into the capacitance formula, we get C = (σA)/ (σd/ϵ₀). 6. Simplifying, we find C = (ϵ₀A)/d.
The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads. Note that capacitance C is ALWAYS positive and never negative. The greater the applied voltage the greater will be the charge stored on the plates of the capacitor.
The greater the applied voltage the greater will be the charge stored on the plates of the capacitor. Likewise, the smaller the applied voltage the smaller the charge. Therefore, the actual charge Q on the plates of the capacitor and can be calculated as: Where: Q (Charge, in Coulombs) = C (Capacitance, in Farads) x V (Voltage, in Volts)
