When several capacitors are joined so that the same charge passes through each in turn, the combined value is

  • A.the reciprocal of the sum of the reciprocals
  • B.the sum of the individual values
  • C.the product of the values divided by their difference
  • D.the smallest of the individual values

Answer: A

The same charge appears on each and the voltages add, so the reciprocals combine. The result is always smaller than the smallest member, which is the counterpart of resistances in parallel and the reason a series string is used to share a high voltage.
