its own currentto the brusheS;, the safe current output of this generator is30 amperes. Suppose there are 250 ft. of this ^o. 10 wire on thisannature. The resistance of the wire according to the wir-ing table is 1.02 ohms per 1^000 ft. Tlie Dynamo 1051 The resistance of all the wire on the armature… … Fig. 445 half of 0.128 or 0.064 ohm. The drop, or loss of pressurein the armature will be I x E or 30 x 0.064=1.92 or say 2volts. This machine being a shunt generator, the maincurrent does not pass through the fields, and there is nofurther voltage lost. 1052 Steam Engineering The electro-motive…
