amed the coefficient of selfinduction. On account of self induction, no really instantaneouschange of current can take place, and the response tovariable voltage will depend on this feature of the coiland on the rate at which we attempt to make currentchanges. Each coil is an individual in this… … Fig. 24. Oscillogram—Induction coil currents with Wehnelt interrupter.54 X-RAY PHYSICS 55 Tubes for Use with Coils. The current wave through a coil is quite different fromthat from a transformer. The current consists of a seriesof short rushes with considerable time between each im-pulse. Fig. 23…
