of gravity. The coil of m^, is connected across thealternator terminals or station bus-bars, the p.d. between which is to bemaintained constant at all loads. The position taken up by the core of m^and therefore the position of the lever l^ depends on the p.d. between thebus-bars; if the latter… … Fig- 351 the contact k against the tension of the spring s. The field rheostat beingno longer short-circuited, the p.d. of the dynamo falls, the pull exerted bym-^ decreases causing the contact k to close again, upon which the cyclerecommences. If now the p.d. of the bus-bars falls, due say to an…
