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.
What is difference between volt ampere and watt rating?
Watt rating is the amount of real power that is absorbed (or supplied). VA is normally the units given to the total complex power which is made up of the real power and reactive power. The formula for complex power is as follows. S = P + jQ P is the real power which is used by the resistive elements of the component while the reactive power (imaginary power) is that power which the capacitive and inductive parts of the circuit cause to flow. Watt ratings are always lower (or equal) to the VA rating due to the fact that it neglects imaginary power that is flowing, because of this both ratings should be taken into account.
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....
Define Real Power?
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.
