The real power in a DC system is the product of voltage & current. P = V * I
In an AC system the power is equal to V * I * power factor. The power factor allows for the fact that the power is less than the volt-amps. This happens when the voltage and current are out of phase, i.e. if they reach their peak value at different points in the AC cycle. In fact if the phase difference is exactly 90 degrees, no real power is transferred at all, although the transmission wires still have to carry current and produce power losses as a result,
The real power (in watts) is defined as the volt-amps times the cosine of the phase difference between voltage and current. Using the convention of complex numbers, the 'imaginary' power (in volt-amps-reactive or VAr) is defined as the volt-amps times the sine of the phase difference.
The three quantities are connected by the Pythagoras formula:
(VA) squared = (watts) squared + (VAr) squared.

Define a complex number using c structure?

Power factor formula?
Power factor is defined as the ratio of real power over total power. Total power is the vector sum of real and reactive power.
The power factor represents?
power factor=real power/apparent power... real power in the sense the capacity of the circuit for performing a work in a particular time..for example the work done by a motor circuit is so and so...real power is what we consume from them... apparent power if the product of the current thro' the circuit and the voltage...it will be always greater than the real power.. if the POWER FACTOR IS 1.0(100%),THEN THE AC POWER IN THE CIRCUIT WILL BE EQUIVALENT TO THE POWER OFFERED BY A DC CIRCUIT....
Is it possible for an energized circuit at 240 volts and 100 amps but no power?
Yes if you are referring to no real power, no if you are saying no power (real or reactive). You could have 100A flow from a capacitor bank or inductor bank, which should consume no real power, but provide voltage support / pull down when on line by introducing reactive power to the system.

How do you define real?
Real is something that is real or existing or occurring as fact. It is also means it is not fake.It is realistic.
are u real?
Ofcourse i am. I said i am real and i am because realness define yourself. I am real and enclosed the image. Thank you.
How do you define real difference?
It is when two sets of ranges do not overlap
What is define real number?
It is a bit hard to define them - and the exact definitions are a bit formal. It is best to think of real numbers as the equivalent of all points on a straight line, infinite in both directions.

What is an example of the Thomas Theorem in Lord of the Flies?
The conch shell could be seen as an example, because it has no actual ability to let only one person speak, but "If men define situations as real, they are real in their consequencesIf men define situations as real, they are real in their consequences", so the conch shell becomes real in its consequence.
