Three capacitors of 1.0,1.5,and 2.0 mF are connected in series.Find the combined capacitance.
A)4.5 mF
B)4.0 mF
C)2.2 mF
D)0.46 mF

Question

Quizplus · Accepted Answer

When capacitors are connected in series, the reciprocal of the combined capacitance is equal to the sum of the reciprocals of the individual capacitances.

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

Substituting the given values, we get:

1/C = 1/1.0 + 1/1.5 + 1/2.0

1/C = 0.6

C = 1/0.6 = 1.67 mF

Therefore, the combined capacitance is 1.67 mF, which is closest to option D (0.46 mF). None of the options provided is correct.
