What is the average power consumed in an AC circuit with a power factor of 1? (2019)
Step 1: Understand that in an AC circuit, power can be measured in terms of voltage and current.
Step 2: Know that 'V_rms' stands for the root mean square voltage, which is the effective voltage in the circuit.
Step 3: Know that 'I_rms' stands for the root mean square current, which is the effective current in the circuit.
Step 4: Recognize that the power factor is a measure of how effectively the current is being converted into useful work, with a power factor of 1 meaning all the power is being used effectively.
Step 5: Use the formula P = V_rms × I_rms to calculate the average power consumed when the power factor is 1.
