The statement that true power will always be greater than apparent power is false.

In electrical systems, true power is the actual power consumed by the load to perform work and is measured in watts (W). Apparent power, on the other hand, represents the total power flowing through the circuit and is measured in volt-amperes (VA). The relationship between true power and apparent power is influenced by the power factor of the load.

The power factor is a measure of how effectively the electrical power is being converted into useful work output and is a ratio that compares true power to apparent power. In purely resistive loads, where there is no reactive power (like in heaters), true power and apparent power can be equal. However, in inductive or capacitive loads, true power is less than apparent power due to the presence of reactive power.

Therefore, saying that true power will always be greater than apparent power is misleading, as it can indeed be less than or equal to apparent power depending on the load and its power factor.
