That is, the load resistance must be greater power factor is equal to 1. It means that the voltage and electric current there is no phase difference. Due to the power factor measurement of power consumption is approximately created.They make no devices measuring power factor as standard gauge to measure and compare. But from a different angle calculated from the phase of the signal, the voltage and current signals.It appears that the value measured is considered close to the calculated value.
