Explanation
In any AC circuit, the apparent power, which is the combination of real power (actual power consumed) and reactive power (power stored and released by reactive components), is always greater than or equal to the real power alone. This is because apparent power is the vector sum of real and reactive power, so it cannot be less than real power.
