WebAs with the resistor example, the power is also positive when the instantaneous current and voltage are both negative (below the line). However, because the current and voltage waves are 90° out of phase, there are times when one is positive while the other is negative, resulting in equally frequent occurrences of negative instantaneous power. WebAug 2, 2024 · Φ is the phase angle in degrees. The larger the phase angle, the greater the reactive power. Cos (Φ) = P/S = W/VA = power factor, p.f. Sin (Φ) = Q/S = VAr/VA. Tan (Φ) = Q/P = VAr/W. The power factor is calculated as the ratio of the real power to the apparent power because this ratio equals cos (Φ). daehan technologyWebCircuit with a 6 V battery, two 10 ohm resistors and a 20 ohm resistor in parallel. ...
