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?

Answer Posted / pdbhatt69
If total loss in cable is 3 Kw hence it must be devided n
al 3 phases and hence 1 KW loss in one phase, now you can
use frmula P=I*I*R.It comes around 2.083 Milli ohm.
