Yes. Power factor is never greater than one, nor less than negative one. It is the cosine of the phase angle, and is the ratio of true versus apparent power.
A negative power factor can occur in the case of a generator.
Transformers are rated in KVA. (this is because the transformer is Unity power factor device i.e.. PF = 1)AnswerThe selection of a transformer is determined by the apparent power of the load, expressed in volt amperes(V.A), the load current, and the line voltage of the supply. The transformer must be able to satisfy these requirements.Transformers are not 'unity power factor' devices, which is precisely why their capacity is expressed in volt amperes, rather than in watts.
No.
No, it's never greater than the smallest number.
No. In the simple case of a linear circuit, the power factor is the cosine of an angle, and that can't be more than 1.
The only common factors of 38 and 90 are 1 and 2, so it is not possible for a common factor of 38 and 90 to be greater than 2, much less 20.
Power factor cannot exceed unity!
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 the 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.
not possible. power factor is an cosine angle between current and voltage...
What is the question for this situation
4 is greater than 3 and is a factor of 20.
7 is an odd factor of 14 greater than 1
15 is a number greater than 10 and a factor of 30.
It means that one factor is greater than (>) or less than (<) some other factor.
No. No number can have a factor greater than itself.
The terms (factors) used in multiplication are the multiplicand (the factor being multiplied), the multiplier (the factor that the multiplicand is multiplied by) and the product (the answer, or results of the multiplication). Any time either of the factors is greater than the other by at least one, the product will always be greater than the largest factor.
Power Factor measures the difference in phase between the current and voltage. When they are in phase the Power Factor is defined as 1. When out of phase the value is less than 1. If they are 180 degrees out of phase the Power Factor will be zero.
Inductive loads have a power factor of less than 1, which means the apparent power is greater than the active power in these circuits. This is due to the lagging power factor caused by the inductive components in the load.
