What is the power consumed by a device that operates on 12 volts and draws 7 amps?

To determine the power consumed by a device that operates at a certain voltage and current, you can use the formula:

Power (P) = Voltage (V) × Current (I)

In this instance, the device operates at 12 volts and draws 7 amps. By substituting these values into the formula:

P = 12 V × 7 A = 84 W

This calculation confirms that the power consumed by the device is 84 watts. The correct answer is based on using the relationship between voltage, current, and power accurately, demonstrating an understanding of basic electrical principles. Other answers represent different calculations or misunderstandings of how power consumption is derived from these two fundamental electrical measurements.
