                                                       S=   ∑ i x L
                                                               ?U x K
                            
 Where,
                                       S =Cross Sectional area
                                       ∑i=Total Current
                                       L=Loop Length
                                      ?U=Voltage Drop
                                       K=Constant, 57 for copper & 34 for Aluminum
