These windings have no CURRENT APPARATUS. 2673 electrical connection with each other and connect to twodistinct circuits. 3977. Sometimes, instead of using two distinct circuitswith four… … Fig. 1528. collector rings are necessary. If E represent the E. M. F.generated per phase, the voltage between a b and b c will beE, while that between a c will be E 4/2. This will be un-derstood by referring to Fig. 1529, the E. M.
