What is the power factor of an AC circuit with a phase angle of 60°? (2022)

What is the power factor of an AC circuit with a phase angle of 60°? (2022)

Step 1: Understand that the power factor is a measure of how effectively electrical power is being converted into useful work output.
Step 2: Know that the power factor can be calculated using the cosine of the phase angle in an AC circuit.
Step 3: Identify the given phase angle, which is 60° in this case.
Step 4: Use the cosine function to find the power factor: calculate cos(60°).
Step 5: Recall that cos(60°) equals 0.5.
Step 6: Conclude that the power factor of the AC circuit is 0.5.
