In a parallel configuration, capacitors ______ the total capacitance of the circuit.

• A. Decrease
• B. Increase
• C. Multiply
• D. Add

Answer: (B)

In a parallel configuration, capacitors increase the total capacitance of the circuit. This occurs because when capacitors are connected in parallel, each capacitor's plates face the same voltage, effectively allowing each capacitor to store charge independently in addition to the others.

The total capacitance in a parallel arrangement is determined by summing the individual capacitances of each capacitor. This additive behavior results in a greater overall capacitance compared to any single capacitor in that configuration. Mathematically, the total capacitance (C_total) can be expressed as:

C_total = C1 + C2 + C3 + ... + Cn

This characteristic demonstrates how the ability to store more charge is increased with additional capacitors, thereby enhancing overall capacitance in the circuit. In contrast, configurations such as series connections often lead to a decrease in effective capacitance since the total voltage across the arrangement is distributed among the capacitances.
