other will be EG, where G is the total conductance between 

 the wires. So also, if B is the capacity susceptance of the 



Supply

line considered as a condenser, EB will be the value of the 

 shunted current in quadrature 

 with E. 



The vector diagram for the 

 line indicated in Fig. 3 (neg- 

 lecting the voltage drop in the 

 conductors) is shown in Fig. 4. 

 It is seen that the current I a at 

 the supply end is different in 

 magnitude and phase from the current I at the receiver. 



In order to calculate the combined effect of the above 

 phenomena, formulas must be used which will take into 

 account the fact that the resistance, capacity, etc., are 

 uniformly distributed along the line, and that the line cur- 

 rent and voltage are different at all parts of the line.
