A 15 ohm toaster operates on a 120 volt line. What is its power consumption?

To determine the power consumption of the toaster, you can use the formula for electrical power, which is derived from Ohm's Law. The formula for calculating power (P) in watts when you know the voltage (V) in volts and the resistance (R) in ohms is:

P = V² / R

In this case, the toaster operates at a voltage of 120 volts and has a resistance of 15 ohms. By substituting these values into the formula:

P = 120² / 15

P = 14400 / 15

P = 960 watts

This calculation shows that the power consumption of the toaster is indeed 960 watts. This makes the correct choice the one that reflects this power calculation accurately. The values for the other options do not fit the calculation using the standardized formulas in electrical engineering, making them less viable as correct answers.
