Web(The phase angles of resistive and capacitive impedance are always 0° and -90°, respectively, regardless of the given phase angles for voltage or current.) As with the purely capacitive circuit, the current wave is leading the voltage wave (of the source), although this time the difference is 79.325° instead of a full 90°. WebBy using Ohm’s Law, we can calculate the current flowing through each parallel resistor shown in Example No2 above as being: The current flowing in resistor R1 is given as: IR1 = VS ÷ R1 = 12V ÷ 22kΩ = 0.545mA or 545μA. The current flowing in resistor R2 is given as: IR2 = VS ÷ R2 = 12V ÷ 47kΩ = 0.255mA or 255μA.

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).
