There is 3phase power cable from 1 point to the other point which is 100m away. Two point equipped with power meter and recorded 1st point is 205kW while the 2nd is 202kW and each phase average carry 400amps. To calculate the resistance of the 3phase power cable, is the formula using will be P=I2R?
