A two core cable feeds a load at a distance of 750 m from the supply point. Each core has a resistance of 0.01 D. The voltage at the load end of the cable is 275 V. The power delivered to the load is 22.5 kW and the power factor is 0.75 lagging.
Determine:
(a) The current in the cable.
(b) The losses in the cable
(c) The supply voltage.
(d) The cable's input power
