What is the formula for calculating power in an electrical circuit?

Step 1: Understand that power (P) is the amount of energy used in a circuit.
Step 2: Know that power is measured in watts (W).
Step 3: Identify the two important components: voltage (V) and current (I).
Step 4: Remember that voltage (V) is the electrical force that pushes the current through the circuit.
Step 5: Understand that current (I) is the flow of electric charge in the circuit.
Step 6: Use the formula P = V * I to calculate power.
Step 7: Plug in the values for voltage (V) and current (I) into the formula.
Step 8: Multiply the voltage by the current to get the power in watts.
