What is the relationship between power, voltage, and current in a load?

The correct answer highlights the fundamental relationship defined by electrical principles, specifically through the formula for electrical power. Power in a circuit is mathematically expressed as the product of voltage and current. This relationship indicates that as either voltage or current increases, the overall power in the load increases as well.

In practical terms, when you maintain a constant voltage and increase the current flowing through a load, the power delivered to that load will also increase proportionately. Conversely, if you keep the current constant and increase the voltage, power will similarly rise. This direct relationship demonstrates how power, voltage, and current interact with one another within electrical systems, reinforcing the idea that both voltage and current are essential factors in determining the total power consumed or generated by a load.
