Not illustrated. 1913 Excerpt: ...2 Elektrot. ZS., 13, 460; 1892. 15 to 20 volts lower than that for the latter, the current and length of arcs being the same in both cases. The characteristic curves for the flaming arc with alternating current are nearly identical with those for the same arc with direct current. One curve taken by myself for a flaming arc 10 mm. long with alternating current was identical throughout the greater part of its length with that taken with the same carbons and length where a direct current was used, as shown in Fig. 16. Current and Potential Difference at Different Phases.--As far as I have been able to learn the first published work on the alternating-current arc was by Joubert, in 1880,1 who showed the values of the potential difference and the current at different phases of the alternations. His method was the one which is well known in the work on alternating currents, where a measuring instrument is connected to the circuit for a brief length of time during each alternation, the connection being always made at the same phase of the alternation. He found the curve for the current to be nearly a sine curve, while that for the potential difference was greatly deformed. This observation was confirmed by Tobey and Walbridge.2 The form of these curves has been found to vary with the kind of dynamo used, the character of the carbon and the length of the arc.3 The preceding method gave the average value of some 1 C.
