乘积

With this important concept which the reads of wattmeter was equal to the product of the effective value of the voltage across the potential coil, the effective value of the current flowing in the current coil, and the cosine of the phase-angle between the current and the voltage. It was speciled with some examples to determine the phase-angle measured between line voltage, line current in different connection.

Some of the oldest open problems in mathematics relate to the abundancy index of a number. Are there infinitely many perfect numbers? Does there exist an odd perfect number? Does there exist an odd multiply perfect number? Such questions have been considered for well over two millennia by the likes of Euclid, Fermat, Descartes, Mersenne, Legendre, and Euler.
