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). phire water

WebThese equations show that a series RC circuit has a time constant, usually denoted τ = RC being the time it takes the voltage across the component to either rise (across the capacitor) or fall (across the resistor) to within 1 e of its final value. That is, τ is the time it takes VC to reach V(1 − 1 e) and VR to reach V( 1 e) . WebA voltage divider is a simple series resistor circuit. It's output voltage is a fixed fraction of its input voltage. The divide-down ratio is determined by two resistors. Written by Willy McAllister.

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.
