3.1 A copper and an aluminium conductor are connected in parallel to supply a load
of 300A over a distance of 500m. The two conductors have equal cross-sectional
areas of 50mm2. Take the resistivity of coper as 0.018µΩm and that of aluminium as
0.028µΩm and calculate
3.1.1 the total resistance of the two conductors (9)
3.1.2 The voltage drop across the compound line (3)
3.1.3 The current carried by each conductor (6)
