True or false: two capacitors in series always have a combined value smaller than either of them.

  • A.True, the reciprocals adding so that the total falls below both
  • B.False, the combination lying between the two individual values
  • C.False, the combination equalling the sum of the two values
  • D.True, unless one of the two is very much larger than the other

Answer: A

The reciprocals add, so the reciprocal of the total exceeds each individual reciprocal and the total is smaller than the smallest member. When one is much larger than the other the total tends to the smaller one but never exceeds it.
