What is the volt-ampere rating of a device that consumes 14.5 A on a 240 V circuit?

To determine the volt-ampere rating (or apparent power) of a device, you can use the formula:

[ \text{Power (VA)} = \text{Voltage (V)} \times \text{Current (A)} ]

In this case, the device consumes 14.5 A on a 240 V circuit. Applying the values to the formula:

[ \text{Power (VA)} = 240 , \text{V} \times 14.5 , \text{A} ]

Calculating this gives:

[ \text{Power (VA)} = 3480 , \text{VA} ]

The calculated value of 3480 VA is directly related to the power consumed by the device, which is why the correct answer reflects that rating in watts. In electrical terms for AC circuits, volt-amperes can be equated to watts when considering resistive loads, making this calculation straightforward and relevant for the problem at hand.

While other choices provide different values, they do not align with the proper application of the formula given the specified voltage and current, leading to the conclusion that 3480 watts accurately represents the device's power consumption.
