Fig. 138. If the circuit be completed by joining the free end of thecopper wire to the copper plate we proceed thus: 220 ELECTRICITY [CH. XIV Let OA, Fig. 139, represent the resistance of the zinc, AB ofthe acid, BG of the copper, CD of the wire. Draw ON perpen-dicular to OABGD to represent E the… … Fig. 139. Let PAQ and BSR be drawn parallel to ON. Draw GPparallel to ND to meet PAQ in P, and take PQ to representthe difierence of potential between the zinc and the acid.From Q draw QR parallel to ND to meet BSR in R. Let PQ meet ND in T. Then RS=QT. Also PT= 0N= E.M.F. of cell. But PQ is the…
