Power factor is a measure of how effectively electrical power is being used in a circuit. It compares the real power (in watts) to the apparent power (in volt-amperes or VA). The power factor can be calculated using the formula: Power Factor = Real Power (Watts) / Apparent Power (VA). It is important to understand the different units used in power factor calculations: Watts to VA, VARs to Watts, VA to Watts, and Watts to VARs. The Megger method is not directly related to power factor or resistance values.
