What reading level is Electricity in Its Application to Telegraphy, a Practical Handbook Covering the Syllabus of the New Technical Examination book?
To quickly assess the difficulty of the text, read a short excerpt:
The path of the current when the down station only is working is to earth through the U-cirele D-circle coil of the up relay in the direction n to D through the small resistance block, through the key and right coil of the galvanometer to line.
As single current working is only resorted to on short lines, no trouble is experienced as regards capacity, therefore the only point which remains to be dealt with is as to balancing. We know that if more current circulates through the line side of the ...relay than through the compensation side, the relay will mark on depression of the key. This can only occur when the resistance in the rheostat is greater than that of the line. If the resistance be too little the relay will be unaffected.
The galvanometer needle indicates which coLL has the more current.
If your own marks are received on moving the large arm of the rheostat to 4,000 this resistance is too much, as more current is flowing to line than through the compensation circuit. Leaving the 400 arm 74 Balancing.
