Final answer:
The amount of power consumed by a circuit with 120 V applied and a resistance of 12 ohm is 1200 W.
Step-by-step explanation:
The amount of power consumed by a circuit can be calculated using Ohm's law and the formula P = IV, where P represents power in watts, I represents current in amps, and V represents voltage in volts.
Given that the voltage applied to the circuit is 120 V and the resistance is 12 ohms, we can calculate the current using Ohm's law: I = V/R = 120 V/12 ohms = 10 A.
Now, we can calculate the power consumed by the circuit using the formula P = IV: P = 10 A * 120 V = 1200 W.
