The coincidence factor is

  • A.the ratio of peak to average demand
  • B.the product of the load and diversity factors
  • C.the reciprocal of the diversity factor
  • D.the same as the load factor

Answer: C

Correct answer: the reciprocal of the diversity factor

\[ \mathrm{Coincidence\ factor} = \frac{1}{\mathrm{diversity\ factor}} = \frac{\mathrm{group\ maximum}}{\sum \mathrm{individual\ maxima}}. \] It is a fraction not exceeding one and says what proportion of the connected maxima actually coincide. The two express the same fact in inverted forms, which is why quoting which one is meant matters.
