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).

WebOct 27, 2024 · In an AC (sinusoidal supplied voltage and current) circuit, resistor voltage and current are always in phase, the supplied voltage and current are not always in phase. But the current can still be calculated using I = V/Z, where Z is the impedance of the circuit. I don't understand this. phillip phillips where is he nowWebIf they are “in-phase” that is, there is no phase shift then they can be added together in the same way as DC values to find the algebraic sum of the two vectors. For example, if two voltages of say 50 volts and 25 volts respectively are together “in-phase”, they will add or sum together to form one voltage of 75 volts (50 + 25). trysence

"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.

WebApr 12, 2024 · The impedance of the resistor is simply its resistance, which is 1 kiloohm. The total impedance of the series circuit is the sum of the impedance of the capacitor and the resistor: Z_total = Z_c + R = -j15.92 + 1000 = 1000 – j15.92 ohms The magnitude of the voltage across the capacitor can be found using Ohm’s law: V_c = I × Z_c WebSo then, for two ohm resistor to calculate the current here, I would substitute R as two, V is 50, calculate the current. Then for 40 Ohm resistor, I would put V is 50, that's already given, R is 40. Calculate the current, same thing over here. And we are done. We now know current through each resistor. But do you understand, that's wrong.
