Calculate  efficiency  of  the  radial  power  grid  as  shown  in  Figure  B2a  andevaluate the efficiency if the power grid forms a ring network.  Compare theresults. 

Given that distance of AB is 3km, BC is 2km, and the ring line AC is 2.5km. Line  resistance is  0.001Ω/m.    Input  voltage  at  substation  A  is  33kV.    Circuit  output at substation B is 20A and circuit output at substation C is 10A.
