2022年4月28日 · 0. Power factor has to do with the amount of real power. if you have a purely capacitive load, there is no real power flow, thus pf = 0. For purely resistive load, power factor will be 1.0.

2023年10月3日 · For a purely-resistive circuit, the load current is in phase with the supply voltage, so its phase-angle is zero. Since power factor is the cosine of the phase angle, the power factor must be ...

2023年10月3日 · No, as 100% efficiency is not possible.AnswerYes, it occurs at resonance. That is, when a circuit's inductive reactance is exactly equal to its capacitive reactance. This can be achieved by ...

2023年10月3日 · True Power = Apparent Power x Power Factor ...where power factor is the cosine of the phase angle, that is the angle by which the load current either lags or leads the supply voltage.

because semi converter has 1ly 2 thyristor where else full converter has 4 thyrister..thn semi converter the rectification is through rectifier and diodes. but in ful converter no diodes is used ...

2023年10月3日 · If you are asking whether power-factor improvement has any effect on a wattmeter reading, then the answer is no, it doesn't. Improving the power factor of a load has absolutely no effect on the ...

2022年4月28日 · Power factor measures the phase difference between voltage and current. If they are in phase the Power Factor is one.

2022年4月28日 · In an alternator, the load current is supplied by the stator and the excitation is applied to the rotor. When the power factor is low (lagging), more excitation is required to maintain rated ...

2024年5月25日 · The plant factor in a power plant is the ratio of actual energy output to the maximum potential energy output over a specific period of time. It indicates how efficiently the power plant is ...

2023年8月11日 · Power factor is the cosine of the phase angle between voltage and current. It depends on many things, including motor design, actual operating voltage, and load.
