At a power factor of 100%, what is the relationship between real load and total load?

At a power factor of 100%, the relationship between real load and total load indicates that they are equal. Power factor measures the efficiency of the electrical power being used; a power factor of 100% means that all the power supplied is being effectively used for the actual work being performed.

Real load refers to the actual power consumed by the electrical devices to produce work, measured in watts. Total load, which incorporates both real power and reactive power, can also be thought of as the apparent power delivered to the system, measured in volt-amperes (VA). When the power factor is at 100%, the reactive power is zero, meaning that there is no difference between real (watts) and total load (volt-amperes) since all the supplied power is converted into useful work.

As a result, when the power factor is at its maximum of 1.0 (or 100%), the real load equals the total load, confirming that all the energy supplied is used productively, without any losses to reactive power effects.
