Question 43
CapacitorsThe resultant capacitance in the figure above is
- A.15.0 μF
- B.9.8 μF
- C.1.3 μF
- D.0.8 μF
Show the answer and explanation
Answer: D (0.8 μF)
Explanation
The 2 μF and 4 μF in parallel make 6 μF. This is in series with 2 μF, 3 μF and 4 μF: 1/C = 1/2 + 1/3 + 1/6 + 1/4 = 15/12, so C = 0.8 μF.
