What aspect does the power law NOT directly address?

The power law specifically relates to the relationships among power, voltage, and current, encapsulated in the formula ( P = V \times I ). This formula directly addresses how these three variables interact in an electrical circuit.

On the other hand, calculating energy units saved involves evaluating the reduction in energy consumption due to efficiency measures, which is not a direct application of the power law. Similarly, while the correlation of power and equipment capacity is linked to how much power specific equipment can handle, the power law itself isn't focused on capacity as it pertains to operational limits rather than mathematical relationships. The annual operating hours of a device pertain to usage metrics rather than electrical relationships.

Thus, the aspect that is not directly addressed by the power law is the calculation of energy units saved. This involves additional factors and calculations that go beyond the basic relationship the power law describes.
