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.

Answer / k.prakashchandra

Yes

Answer / shyamkr

i think the current I will be the r.m.s value of current not
he average value and P will be the power loss in the cable.
so the formula P =I(r.m.s)2 * R.then this formula will give
the resistance in the ac circuit.
