# What is a power factor?

The Power Factor is an indicator of the quality of design and management of an electrical installation. It relies on two very basic notions: active and apparent power. … The active power P (kW) is the real power transmitted to loads such as motors, lamps, heaters, and computers. The electrical active power is transformed into mechanical power, heat or light. In a circuit where the applied r.m.s. voltage is Vrms and the circulating r.m.s. current is Irms, the apparent power S (kVA) is the product: Vrms x Irms. The apparent power is the basis for electrical equipment rating. The Power Factor λ is the ratio of the active power P (kW) to the apparent power S (kVA): The load may be a single power-consuming item, or a number of items (for example an entire installation). The value of power factor will range from 0 to 1.

# What does power factor mean in math?

power factor is the cosine of the angular difference between current and voltage and must be taken into account to get true power (watts)

# What does a Lagging power factor mean?

underdamped AnswerA lagging power factor describes a situation in which the load current is lagging the supply voltage. This describes an inductive load, such as a motor,… etc.

# What does unity power factor UPF mean?

Unity power factor has a value of 1.0. This means the current and voltage waveforms are in phase. This is only possible if the net load is non-reactive (resistive). If t…he load is either capacitively or inductively reactive, the power factor will be other than unity. If an inductively reactive load such as a motor is offset by a capacitively reactive load such as a PF correction capacitor, it is possible to acheive a net load that has unity power factor. Some loads, such as resistance heaters, are intrinsically non-reactive, and present a unity power factor.

# How do you get power factor?

Single phase PF = Input Watts/Volts x Amps. Three phase PF =Input Watts/Volts x Amps x1.732. Additional Answer You can determine the power factor of a circuit using three in…struments: a voltmeter, and ammeter, and a wattmeter. Multiplying the voltmeter reading by the ammeter reading will supply the value of the apparent power in volt amperes. The wattmeter reading will supply the value of the true power in watts. Divide the number of watts by the number of volt amperes, and that will indicate the power factor of the circuit.

# What does it mean to write each power as a product of the same factor?

102 = 10 x 10 25 = 2 x 2 x 2 x 2 x 2

# What is the meaning of utilization factor in hydro power plants?

the ratio of amount of energy generated during specified period to the energy could have been generated during that period by any palnt is the capacity utilisation factor.

# Are load factor and power factor the same?

No Load factor is average power consumption rate divided by peak power consumption rate over a period of time. Power companies like customers who have very steady consumptio…n rates ......Load factors approaching 1 Power factor is true power / apparent power (kW/kV.A) and is a measure of how efficiently a customer's load consumes power. Certain types of electrical loads consume power more efficiently ( resistive element heating ) and they have a Power factor approaching 1. Other types of load such as old inductions motor are quite wasteful consumers of power and the utility has to provide more current ( amperage ) for the load to convert to real power

# What are the factors and prime factors of 275 in powers?

The factors of 275 are: 1 5 11 25 55 275. The prime factors are: 52 x 11

# What does write each power as a product of the same factor mean in math?

The power refers to the base and exponent, so to write it as the product (multiplication answer) of the same factor you would expand the exponent for example: 7^2 = 7*7 or… 4^6 = 4*4*4*4*4*4.

# What do you mean by wattless current and power factor in AC?

Watts = Current x Voltage x Power Factor In an AC circuit both the voltage and current are sine waves. When they are in phase (waveforms lie over top of one another) the PF is… one. As they become out of phase the PF decreases to zero. This happens when the phase difference is 180 degrees. In this case the positive peak of current is at the same place in time as the negative peak of voltage or vice versa. So when PF is zero you coul say you are getting zero watts. Answer An a.c. load current can be resolved into two components. One, in phase with the supply voltage, and responsible for supplying true power to the load. The other, at right angles to the supply voltage, and responsible for supplying reactive power (e.g. the magnetic field, in the case of a motor). As reactive power is sometimes termed 'wattless power', we can say that the second component of this current is 'wattless current'.

# What is the meaning of poor power factor?

Power factor is the cosine of angle between voltage and current that we all know. And the power factor should be unity or close to unity. Unless if we have the power factor n…ot close to unity or far away from unity is called poor power factor. This termed as poor because it will take large amount of current for the given power. If the large amount of current is drawn from the substation or anything else then the line loss will increase. Line loss is (I^2)R loss. So the current increase line loss will also be increased. So as to avoid such losses every industry should maintain their power factor(Normally in every Industry they maintain .9 and above). Those who are not maintaining power factor will be fined.

# What does zero leading power factor mean?

A 'leading' power factor indicates that the load current is leading the supply voltage. Since power factor is the cosine of the angle by which the load current either leads or… lags the supply voltage (i.e. the load's phase angle), a cosine of 0 corresponds to a phase angle of 90 degrees. So, a power factor of 0 (leading) indicates that the load current is leading the supply voltage by 90 degrees, which means that the load must be purely capacitive.
