Two equal capacitances are connected first in series and then in parallel. The ratio of the effective series capacitance to the effective parallel capacitance is
- A. 1/4Correct
- B. 1/2
- C. 1
- D. 4
Explanation
For two equal capacitors C: series capacitance = C/2; parallel capacitance = 2C. Ratio = (C/2)/(2C) = 1/4.
