Questions & Step-by-Step Solutions
If a circuit has a total voltage of 120V and a total current of 10A, what is the total power in the circuit?
Step 1: Identify the total voltage in the circuit, which is given as 120V.
Step 2: Identify the total current in the circuit, which is given as 10A.
Step 3: Use the formula for power, which is Power (P) = Voltage (V) * Current (I).
Step 4: Substitute the values into the formula: P = 120V * 10A.
Step 5: Calculate the result: 120V * 10A = 1200W.
Step 6: Conclude that the total power in the circuit is 1200W.
Ohm's Law – The relationship between voltage (V), current (I), and power (P) in an electrical circuit, where power is calculated as the product of voltage and current.
