currentto the brushes^ the safe current output of this generator is30 amperes. Suppose there are 250 ft. of this No. 10 wire on thisarmature. The resistance of the wire according to the wir-ing table is 1.02 ohms per 1,000 ft. ■(i;- The Dynamo 1051 The resistance oi all the tvire on the armature is… … Fig. 445 Jialf of 0.128 or 0.064 ohm. The drop, or loss of pressurein the armature will be C x E or 30 x 0.064=1.92 or say 2\olts. This machine being a shunt generator, the main^nr- current does not pass through the fields, and there is nofurther voltage lost. 1052 Steam Engineering The…
