Figure 19.6.2 19.6. 2: (a) Capacitors in parallel. Each is connected directly to the voltage source just as if it were all alone, and so the total capacitance in parallel is just the sum of the individual capacitances.

Since the capacitors are connected in parallel, they all have the same voltage V across their plates. However, each capacitor in the parallel network may store a different charge. To find the equivalent capacitance Cp C p of the parallel network, we note that the total charge Q stored by the network is the sum of all the individual charges:
This arrangement of two electrodes, charged equally but oppositely, is called a parallel-plate capacitor. Capacitors play important roles in many electric circuits. where A is the surface area of each electrode. Outside the capacitor plates, where E + and E – have equal magnitudes but opposite directions, the electric field is zero.
