The equation used to calculate power in relation to voltage and current is Power = Voltage x Current. This relationship is based on the fundamental principles of electrical engineering, specifically the formula derived from Ohm's Law.

Power (measured in watts) represents the rate at which electrical energy is consumed or produced. By multiplying voltage (the electrical potential difference, measured in volts) by current (the flow of electric charge, measured in amperes), you obtain power, providing a direct way to quantify the energy use in an electrical circuit.

This formula is essential for linemen as it helps in determining how much power is being used in a system, which is crucial for designing and maintaining electrical utility systems and ensuring safety and efficiency. Using additional operations like addition, subtraction, or division (as seen in the other choices) does not accurately represent the relationship between power, voltage, and current within the context of electrical energy calculations.
