Which equation represents the relationship between current, voltage, and power?

The relationship between current (I), voltage (V), and power (W or P) is accurately captured by the equation where power equals the product of current and voltage. In electrical systems, power is defined as the rate at which electrical energy is transferred by an electric circuit. When you multiply the current (measured in amperes) flowing through a circuit by the voltage (measured in volts) across that circuit, you get the power measured in watts.

This equation is fundamental in both residential and industrial electrical systems, and it allows for the calculation of power consumption or generation within an electrical context. Understanding this relationship is crucial for utility arborists as they may need to assess the power needs related to equipment and tree care operations in proximity to electrical lines.

The other equations provided relate to different electrical principles:

• The equation involving resistance (Ohm's Law) describes the relationship between voltage, current, and resistance but does not directly define how power is calculated.

• The equation that involves dividing voltage by resistance outputs current, again not relevant to directly finding power.

• The last equation appears to be a manipulation of units but does not accurately express the relationship between current, voltage, and power.

Therefore, the correct equation that represents the relationship between current,
