ow due to the dynamo resist-ance of 600 ohms and the added resistance of 1,200 ohms ar to d^ plus the joint re-sistance of the main and artificial lines and the leak of 900 ohms {See Fig. 177),which gives a total resistance of 2250 ohms. The fall along a single circuit of that resistance would be… … 22^- 225- THE FIELD KEY SYSTEM (THEORY.) namely 45 volts, and the line kg now represents fall of pressure along main line ml;that is, with transmitter open at x. Hence, the potential difference at the terminals of ml coil of ne is, as indicatedby the lines a b and r /, 5 volts; the potential at a…
