Which formula can be used to convert amperage to wattage?

• A. A x V
• B. I + V
• C. A ÷ V
• D. I x V

Answer: (A)

The formula to convert amperage (A) to wattage (W) is derived from the relationship between power, voltage, and current in electrical systems. Power in watts is calculated as the product of current in amperes (I) and voltage in volts (V). Therefore, to find the wattage, you multiply the current (amperage) by the voltage. This principle is established in the electrical formula P = IV, where P represents power (in watts), I represents current (in amperes), and V represents voltage (in volts). When you use A and V in the formula, you are essentially applying this principle correctly. Understanding this concept is crucial because it underpins many applications in electrical systems, allowing technicians to calculate power requirements and ensure safe operation of devices based on their current draw and the voltage supplied.
