Quizplus · Accepted Answer

When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitances. Therefore, the total capacitance of the five identical 3.5 mF capacitors is 5 x 3.5 mF = 17.5 mF. The least possible capacitance of the combination is still 3.5 mF since you cannot have less than one capacitor in the circuit. Therefore, the closest option to 3.5 mF is option C, which is 0.70 mF.
