SUMMARY
The discussion focuses on the relationship between current, voltage, and power in electrical systems. It establishes that power (W) can be expressed in terms of current (A) and voltage (V) using the equations A = C/s and V = J•C^-1. The simplification leads to the conclusion that power is equivalent to J/s, which is defined as watts (W). Therefore, the units of power are confirmed to be watts, demonstrating a clear understanding of electrical unit conversions.
