Quizplus · Accepted Answer

When capacitors are connected in series, the equivalent capacitance is always less than the smallest individual capacitor in the series. Therefore, the equivalent capacitance must be less than 5 µF, making D correct. Additionally, the equivalent capacitance of a series combination is always less than any individual capacitor in that series, making E correct as well.
