How do you find power input with given power factor and power output?
Output Power divided by Power Factor.
What are the advantages and disadvantages of unity power factor?
There is no disadvantage of unity power factor, because at unity power factor all the electrical power is efficiently utilized by the the load, and at lagging power factor some power is lost in the load's magneticfield.
Why you use low power factor wattmeter on primary and unity power factor on secondary side of transformer?
There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.
What is PFI panel?
Power Factor Improvement Panel. It controls power factor
Can we improve generator power factor for increasing active power?
The 0.8 Power Factor provided by generator manufacturers is not the load power factor, but it is the nominal power factor used to calculate the kW output of an engine to supply the power for a particular alternator kVA output. Alternators are therefore designed to supply their rated kVA at 0.8 lagging power factor.
What the answer to factor r2 plus 12r 27?
(r + 9)(r + 3)
Is 2 to the second power divided 3 to the second power a prime factor of 54?
2 to the second power is 4, which isn't a factor of 54. 3 to the second power is 9, which is a factor of 54 but isn't prime. 4 divided by 9 is 4/9, which isn't prime and isn't a factor of 54.
What is the answer to Factor r2-12r plus 27?
r^2 - 12r + 27 what two factors of 27 add up to - 12? (r - 3)(r - 9) FOIL that and get the quadratic polynomial back
What is the algebraic equation if 12 is the perimeter the scale factor is r and the new perimeter is p?
12r = p
What is the greatest common factor of 12x to the second power and 9xy to the second power?
3x
What is the answer to 12r plus 4 equals 112?
12r + 4 = 112, 12r = 108, r = 9
What is 12r-8-12 simplified?
12r - 20
What is the greatest common factor of a to the third power b and a to the second power b to the second power?
The GCF is a^2b
What is 12r-8-12 equals?
12r-20
How do you factor 9r squared minus 12r plus 4?
(3r - 2)(3r - 2) or (3r - 2) squared.
How do you write the power of 4 as a product of the same factor?
4 to the second power
What is 12r- 8- 12 equals?
It is 12r - 20 or 4*(3r - 5)
