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 ...

When the switch is in position A, the capacitor C gains a charge Q 0 so that the pd across the capacitor V 0 equals the battery emf. When the switch is moved to position B, the discharge process begins. Suppose that at a time t, the charge has fallen to Q, the pd is V and there is a current I flowing as shown. flowing as shown.
