An illustration from An introduction to the theory of electricity, with numerous examples, 1876, leaf 176
of a double dividedcircuit, two points in the divided branches being joined by aconducting wire. These divided circuits are ABC and ADC,and BD is the joining wire. In the portions AB, BC, CD, DA,are introduced resistances, which we shall callp, qj s, r, and iiBD is a galvanometer whose resistance… … The current-strengths in the various branches we denoteby 7^, 7j, Jg, /„ I„ J,, as shown in figure. Then in circuit EABCE we have E=BI+pI, + qT, (i), in ABD, 0 =pl,+gl,-rl, (ii), in BCD, 0 = qI,-sT,-gI, (iii), at^, 1=1^ + 1^ (iv), at C, I=^I^ + I, (v), at 5, J;=J,-1-I,... (vi). These six equa,tions…
