Which formula is correct to find the equivalent of 3 capacitors in a parallel circuit?

• A. CT = C1 + C2 + C3
• B. CT = C1 * C2 * C3
• C. CT = C1 / (C2 + C3)
• D. CT = (C1 + C2) * C3

Answer: (A)

In a parallel circuit, the total capacitance is determined by the straightforward summation of all individual capacitances. This is because, in a parallel configuration, each capacitor is connected across the same two points, allowing the total capacitance to be the sum of the capacitances of all capacitors connected in parallel. When capacitors are arranged in parallel, they each provide an additional path for charge storage, leading to an increase in the total capacitance. To find the equivalent capacitance (denoted as CT) of multiple capacitors in parallel, the formula CT = C1 + C2 + C3 accurately captures this additive nature. Therefore, when tasked with calculating the total capacitance for three capacitors connected in parallel, one simply adds the individual capacitances together. This principle can be extended to any number of capacitors; thus, the provided formula effectively showcases the behavior of capacitors in parallel circuits.
