In a certain balanced three-phase system each line current is 5 a and each line voltage is 220 v what is the approximate real power if the power factor is 0.7?
154
What significance has a power factor in an unbalanced system?
A three-phase 'unbalanced' system refers to the load, as the supply voltages are unaffected by load. So the phase-angle and, therefore, the power factor of each phase will be different -i.e. there will be three different power factors.
What is the harmonic factor in a power system?
Two factors reduce the power used by a piece of equipment compared to the volt-amps drawn from the supply: power factor and harmonic factor. Both factors increase the power transmission losses incurred in supplying a given amount of power.The power factor is less than 1 when voltage and current are out of phase with each other.When they are in phase the power equals the volt-amps except for a nonlinear load with a current that is not proportional to voltage. This generates harmonics in the current and the effect is that the power is less than the volt-amps, by an amount equal to the harmonic factor.
How can you have 3 devices that run on 2400 watts each on a 10 amp circuit?
Watts = Volts x Current x Power Factor. Power Factor is one for resistive loads and less than one for reactive loads. If you assume 80% load factor on your 10 amp circuit that is 8 amps. So each of three devices would have to operate on 2.66 amps. To do this the applied voltage for each device would have to be 900 volts.
What is the effect on the supply current if the capacitor is removed?
It depends on how the capacitor is connected and whether the supply voltage is a.c. or d.c. Assuming you are talking about a power-factor improvement capacitor (connected in parallel with an inductive load, supplied with a.c.), then the supply current will reduce.
Write each power as a product of the same factor 7squared?
112
Does evaluate each expression and write each power as a product of the same factor mean the same thing?
yes
How do you write a power as a product of each factor?
103 = 10 x 10 x 10
How to write each power as a product of the same factor?
5^3 = 5 x 5 x 5
What does it mean when a math problem says Write each power as a product of the same factor?
10 to the third power equals 10 times 10 times 10
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.
On your math homework the directions are Write each power as a product of the same factor What does this mean and please add an example?
3 to the third power = 3 x 3 x 3
How can you find the product of mixed numbers?
step 1 write each mixed number as an improper fraction step 2 look for common factor and simplify step 3 multiply write the product as a mixed number
What are the steps for greatest common factor?
Step 1 : Prime Factorise each number and write in index notation. Step 2 : Multiply the lowest power of each common factor of the given numbers
When two numbers or more multiplied each number is called a product?
Each number is called a factor. The answer is the product.
What does it mean that the product is greater than each factor?
In the equation 4 x 9 = 36, the product (36) is greater (larger) than each factor (4 and 9).
What does this mean Write each power as a product of the same factor Then find the value of the product?
The question is probably showing how to multiply numbers that are to powers but have different bases that are factors of each other using power rules rather than a calculator. Example: 2^13 x 8^2 = 2^13 x (2^3)^2 = 2^13 x 2^6 = 2^(13+6) = 2^(19). You can double-check answers with a calculator.
