To determine the number of amps required to operate a device rated for 1500 watts at 120 volts, we can use the formula relating watts (W), volts (V), and amps (A):

[

\text{Amps} = \frac{\text{Watts}}{\text{Volts}}

]

Substituting the given values:

[

\text{Amps} = \frac{1500 \text{ watts}}{120 \text{ volts}} = 12.5 \text{ amps}

]

This calculation shows that a device rated for 1500 watts at 120 volts requires 12.5 amps to operate, confirming that the choice of 12.5 Amps is indeed accurate.

Understanding this formula is essential for electrical calculations, as it allows for the determination of the current needed to safely operate devices without overloading circuit components. It's critical for technicians to be able to accurately calculate these values to ensure compliance with safety standards and to prevent circuit overloads that could lead to equipment damage or hazardous conditions.
