What reading level is Electricity At the Paris Exposition of 1889 book?
To quickly assess the difficulty of the text, read a short excerpt:
The double relay is in the line circuit, and consists of a suspended double bobbin, capable of turning in the field of a strong magnet, one of which bobbins responds to a negative and one to a positive current. The dials are turned by clockwork controlled by this relay. A certain number of positive impulses brings all the dials to the corresponding number ; this is followed by a negative im- pulse, and then by the number of the calling station, after which the two are in communication, all the ...others being excluded by the fact that their receivers are cut out of the line circuit by their dials. All the dials are brought back by one of the operators by sending a suffi- cient number of impulses to bring his dial back to zero. It is used chiefly for railroad and other similar service, in which a number of stations are on one line. It has been in very satisfac- tory use for a year on the Paris, Lyons and Mediterranean Railroad between Paris and Lyons, a distance of about 320 miles, with eleven stations, 011 No.
