Which measurement indicates the power output capacity of a tool?

The measurement that indicates the power output capacity of a tool is wattage. Wattage represents the rate at which electrical energy is converted into mechanical energy or work. It is calculated by multiplying voltage (the force of the electrical flow) by current (the flow of electricity), which can be simplified to the formula: Power (Watts) = Voltage (Volts) x Current (Amperes). Therefore, wattage directly reflects how much power a tool can use during operation, making it vital for understanding the capabilities and efficiency of the tool.

While amperage and voltage rating are important, they alone do not provide a complete picture of a tool's power output capacity. Amperage indicates the amount of electrical flow, and voltage denotes the potential difference in electrical energy. However, wattage combines both elements to give a clearer understanding of how much work the tool can perform. Thus, wattage is the accurate measure of a tool's power output capacity.
