What is the formula for calculating total capacitance in a parallel circuit?

• A. C_total = C1 × C2 × C3
• B. C_total = C1 + C2 + C3
• C. C_total = C1 - C2 - C3
• D. C_total = (C1 + C2 + C3) / 3

Answer: (B)

In a parallel circuit, the total capacitance is calculated by simply adding the capacitances of each capacitor connected in parallel. This happens because each capacitor provides an additional "path" for the charge to accumulate, effectively increasing the total capacitance. As the voltage across each capacitor in parallel remains the same, the total capacitance is the sum of each individual capacitance, represented by the formula \( C_{total} = C_1 + C_2 + C_3 \). This relationship can be visualized as the capacitors collectively sharing the same voltage while allowing their charge storage to combine, leading to a greater overall capacitance compared to individual capacitors. Therefore, this formula highlights how capacitors interact in a parallel configuration, resulting in enhanced capacity for charge storage.
