es arc lamp the shunt coil is used to regulate thevoltage over the arc. With constant potential arc lampsthis shunt coil is not needed^ owing to the fact that thevoltage over the lamp is practically constant. Fig. 672shows a diagram of an arc lamp for use on constant poten-tial circuits. The upper… … Fig. 672 and through the resistance coil E to the other terminal ofthe lamp. The action of the lamp is as follows: Currentpassing over the solenoids M M is regulated by the resist-ance across the arc. This current produces an electromag-netip pull on the iron core and floats^ magnetically^ the…
