WebQ factor: Q factor or quality factor of a tuned circuit is defined as the ration of reactance to the resistance of the circuit. It is also defined as the total energy stored to the energy lost by the system. Significance : Q factor determines the sharpness of the resonance curve, if Q is high, the resonance curve is sharper and the energy lost by the circuit is less. WebA high power factor indicates that the power supplied to the electrical system is effectively used. A system with low power factor doesn’t effectively consume the incoming electric …
WebThe power factor for the circuit, overall, has been substantially improved. The main current has been decreased from 1.41 amps to 994.7 milliamps, while the power dissipated at the … WebMay 17, 2024 · We know that power factor (pf) is an important parameter for calculation of power in an AC circuit. For a given power and voltage, the current flowing through the line is inversely proportional to the power factor. This means that a poor power factor i.e. low power factor will result in higher load current and hence higher losses.
WebThe power factor represents the fraction of the available power (also called apparent power) that is consumed (also called the true power) by the circuit. Low power factors cause …
