ebox so tliat all the resistance is in circuit. A rheostat con-sists of a number of resistances, Figs. 461 and 462, so ar-ranged that they can be cut in or out of the circuit ^tith-out opening the circuit. By reference to Fig. 462, it willbe seen that the current enters at the handle, and fromthere… … Fig. 462 Rheostats for the shunt circuit of a dynamo should havesufficient resistance, so that when it is all inserted, thevoltage of the dynamo will slowly sink to zero. Thismethod of stopping the action of a dynamo is perfectlysafe, and should be followed wherever possible. We are now running our…
