Capacitance in Parallel When capacitors are connected in parallel, the effective plate area increases, and the total capacitance is the sum of the individual capacitances. Figure 1 shows a simplified parallel circuit. The total charging current from the source divides at the junction of the parallel branches. Fig. 1 - Simplified parallel circuit.

Capacitors react against changes in voltage by supplying or drawing current in the direction necessary to oppose the change. When a capacitor is faced with an increasing voltage, it acts as a load: drawing current as it stores energy (current going in the positive side and out the negative side, like a resistor).

The expression in Equation ref{8.10} for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference (V = q/C) between its plates.
