In capacitors connected in parallel, how is the total capacitance calculated?

• A. C = C₁ x C₂ x C₃
• B. C = C₁ + C₂ + C₃
• C. C = C₁ - C₂
• D. C = 1 / (1/C₁ + 1/C₂)

Answer: (B)

In a parallel connection of capacitors, the total capacitance is calculated by simply adding the capacitances of the individual capacitors together. This stems from the principle that when capacitors are connected in parallel, they each provide a separate path for the electrical charge. When you connect capacitors in parallel, the voltage across each capacitor remains the same, and the total charge stored in the system is the sum of charges stored in each capacitor. Since capacitance is defined as the charge stored per unit voltage (C = Q/V), if the voltage is constant across all capacitors, the total capacitance (C) is the sum of their individual capacitances (C₁, C₂, C₃, etc.). Therefore, the equation C = C₁ + C₂ + C₃ accurately reflects how total capacitance is calculated for parallel capacitors. This addition of capacitances in parallel is a fundamental concept in circuit theory, as it allows for increased total energy storage in electric circuits.
