What is the total power consumed in a circuit with a power factor of 0.6, if the apparent power is 100 VA? (2023)
Step 1: Understand the terms. Apparent power (measured in VA) is the total power in a circuit, while real power (measured in W) is the actual power consumed.
Step 2: Identify the power factor. The power factor is a number between 0 and 1 that shows how effectively the apparent power is being used. In this case, the power factor is 0.6.
Step 3: Use the formula to find real power. The formula is P = Power Factor × Apparent Power.
Step 4: Plug in the values. Here, the apparent power is 100 VA and the power factor is 0.6. So, P = 0.6 × 100 VA.
Step 5: Calculate the result. Multiply 0.6 by 100 to get 60 W.
Step 6: Conclusion. The total power consumed in the circuit is 60 W.
