The formula P = E x I is a fundamental equation in electrical engineering that describes the relationship between power, voltage, and current. In this context, P represents power, measured in watts, E represents voltage, measured in volts, and I represents current, measured in amperes (amps).

This equation illustrates that power is directly proportional to both voltage and current. When either voltage or current increases, the power consumed by an electrical device also increases. This relationship is essential for understanding how electrical systems operate and for calculating energy consumption in various applications.

The option related to resistance, current, and voltage, while important in electrical calculations, does not accurately describe the specific relationship established by the P = E x I formula. Resistance is typically measured using Ohm's law, while current and voltage might be involved in other calculations or formulas but are not the correct focus for this specific equation. Thus, the assertion that the correct answer is the power consumed in watts is indeed valid within this framework.
