Compute the total capacitance in microfarads (μF) of a parallel circuit containing two capacitors: 5 μF and 10 μF.

• A. 0.3 μF.
• B. 3.33 μF.
• C. 15 μF.
• D. 50 μF.

Answer: (C)

In a parallel circuit, the total capacitance is simply the sum of the individual capacitances. This principle applies directly to the capacitors in question: one with a capacitance of 5 μF and the other with a capacitance of 10 μF.

To find the total capacitance:

1. Add the capacitance values together:

Total Capacitance = 5 μF + 10 μF

Total Capacitance = 15 μF

This calculation demonstrates that when capacitors are connected in parallel, their capacitances combine directly, leading to a larger total capacitance that is equal to the arithmetic sum of each capacitor's capacitance. As such, for this configuration, the total capacitance achieved is indeed 15 μF, making it the correct answer.
