Abstract
WE can recommend this pocket-book to all who are practically engaged in any of the industries in which electricity is used. This edition has been revised and contains new sections dealing with tungar rectifiers, railway signalling and current limiters. The latter are devices which either cause the consumer's lamps to flicker in an intolerable way or to become dim if he tries to take more than his permissible current.
