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 smaller the potential difference | ∆ V | for a fixed Q.
A capacitor can be charged by connecting the plates to the terminals of a battery, which are maintained at a potential difference ∆ V called the terminal voltage. Figure 5.3.1 Charging a capacitor. The connection results in sharing the charges between the terminals and the plates.
