Q = Q 1 + Q 2 + Q 3. (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. (b) The equivalent capacitor has a larger plate area and can therefore hold more charge than the individual capacitors.
The equivalent capacitor for a parallel connection has an effectively larger plate area and, thus, a larger capacitance, as illustrated in (Figure) (b). Total capacitance in parallel Cp = C1 +C2 +C3 +... C p = C 1 + C 2 + C 3 +... More complicated connections of capacitors can sometimes be combinations of series and parallel. (See (Figure).)
When 4, 5, 6 or even more capacitors are connected together the total capacitance of the circuit CT would still be the sum of all the individual capacitors added together and as we know now, the total capacitance of a parallel circuit is always greater than the highest value capacitor.
For a parallel-plate capacitor in a vacuum the capacitance is exclusively determined by the geometry of its arrangement. It is directly proportional to the area A of the plate and inversely proportional to the dis-tance d between the plates: How can the proportionality C 1/d be illustrated? (Hint: Consider the electric field E and the voltage
Cp = C1 + C2 + C3. This expression is easily generalized to any number of capacitors connected in parallel in the network. For capacitors connected in a parallel combination, the equivalent (net) capacitance is the sum of all individual capacitances in the network, Cp = C1 + C2 + C3 +... Figure 8.3.2: (a) Three capacitors are connected in parallel.
The total capacitance of this equivalent single capacitor depends both on the individual capacitors and how they are connected. Capacitors can be arranged in two simple and common types of connections, known as series and parallel, for which we can easily calculate the total capacitance.
