rents the frequency may reach 200. Thefrequency is increased (1) by diminishing the size of theanode point, (2) by raising the temperature of the acid, (3)by diminishing the self-induction in circuit. Some self-induction is, however, essential or there will be no inter-ruptions. A condenser across… … Fig. 38.—Wehnelt interrupterwith perforated tube round leadanode (Schall). The energy required is diminished by raising the tempera-ture and (slightly) by using stronger acid. It is found that to get the same spark-length, amore powerful coil is required withthe Wehnelt than with any otherbreak. An…
