How to find the power factor?
Understand the Problem
The question is asking how to calculate the power factor, which is a measure of how effectively electrical power is being used in a system. It involves understanding the relationship between real power, apparent power, and reactive power in an AC circuit.
Answer
PF = P / S
The final answer is PF = P / S
Answer for screen readers
The final answer is PF = P / S
More Information
Power factor is crucial in electrical systems because it indicates how effectively electrical power is being used. A low power factor means poor efficiency and results in higher energy costs.
Tips
A common mistake is to confuse real power (P) with apparent power (S). Remember, real power is in watts (W) and apparent power is in volt-amperes (VA).
