of wire revolving in amagnetic field to sHp rings, they be attached one to eachhalf of a split metal ring mounted on the same shaft, thetwo halves being insulated from each other, and brushes beprovided, which are so placed that at the instant the inducedE.M.F. in the loop changes in direction the… … a commutator^ is employed when it is desired to obtain a recti-fied, continuous or direct current. A dynamo so equippedis called a direct-current generator, or simply a generator. If the loop were wound double, i.e. have four conductors,before the ends were attached to commutator segments,and if…
