ent passes through these coilsthey draw in the cores and in so doing increase the Arc Lamps 215 reactance of the circuit. This in turn cuts down thecurrent. In the above manner the device automatic-ally regulates the current and keeps it very close toits predetermined value. This device is used… … Figure 142 erator always passes through it. This current inducessecondary currents in the coil S. This coil is balancedby the weights W, and is free to move up or down.If the current in the secondary increases beyond apredetermined amount, the repulsion between the twocoils is increased and the…
