Parallel plate capacitors are formed by an arrangement of electrodes and insulating material. The typical parallel-plate capacitor consists of two metallic plates of area A, separated by the distance d. Visit to know more.
0 parallelplate Q A C |V| d ε == ∆ (5.2.4) Note that C depends only on the geometric factors A and d.The capacitance C increases linearly with the area A since for a given potential difference ∆V, a bigger plate can hold more charge. On the other hand, C is inversely proportional to d, the distance of separation because the smaller the value of d, the …
