Arc Lamp Coil and Plunger {sad; the travel of the plunger a E. The length of the plungermust be equal to D a b Ji, where D a \s equal to b E, or theplunger twice the length of the coil. The maximum pull is just about where the ends of the coil andplungers coincide at <5. If the plunger is… … Fig. 215.—Diagram of Power in Coil and Plunger pull becomes less and less till it is zero, when the plunger projectsequally from each end. Now the important question that arises in designing lamp coilsand plungers, is, at what point in the pull curve should the end ofthe plunger operate ? Should it…
