What is the power consumed by a 120V AC circuit with a current of 3A?
Steps
Concepts
Step 1: Identify the voltage (V) in the circuit. In this case, V = 120 volts.
Step 2: Identify the current (I) in the circuit. Here, I = 3 amperes.
Step 3: Use the formula for power (P) in an electrical circuit, which is P = V * I.
Step 4: Substitute the values into the formula: P = 120V * 3A.
Step 5: Calculate the power: 120 * 3 = 360 watts.
Step 6: Conclude that the power consumed by the circuit is 360 watts.
