...the readings of two single-phase watt-hour meters installed on the supply circuit. From the tangent of the angle of lag, the cosine of the angle of lag, or power factor, is determined by reference to the standard tables. The "demand," or the figure from...

...an alternating current system is equal to the product of the effective current by the effective emf multiplied by the cosine of the angle of lag. The cosine of the angle of lag is called the power factor. Example. Assume an angle of lag of 49° 14' 9" and calculate the power, the...

...current and pressure readings or apparent power = 20 X 110 = 2,200 watts The true power is the product of the apparent power multiplied by the cosine of the angle of lag. Cos 45° = .707, hence true power = 2,200 X .707 = 1.555.4 watts. Ones. Does the power factor apply...

...average power (or the true power) is equal to the effective current, times the effective voltage, times the cosine of the angle of lag. The cosine of the angle of lag is called the "power factor," and is the per cent that the "true power" is of the "apparent power." The...
