Quizplus · Accepted Answer

When capacitors are connected in series, their effective capacitance is given by:

1/C = 1/C1 + 1/C2 + 1/C3 + ...

In this case, plugging in the values we get:

1/C = 1/0.60 + 1/1.2 + 1/2.9
1/C = 1.6667
C = 0.6 μF

Therefore, the combined capacitance is 0.35 μF (closest to D).
