Book Description
Excerpt from Journal of the Institution of Electrical Engineers, Late the Society of Telegraph-Engineers and Electricians, Vol. 32: Including Original Communications on Telegraphy and Electrical Science; May, 1903 Mr. M. Solomon: I should like to add a few remarks to what has yeti-0mm already been said on the Nernst lamp, especially with reference to Professor Ayrton's comments on the candle-power curves shown by Mr. Drake. Of course one does not always get such good results as these, especially so good as those in the curve in Fig. A, which repre sents the mean result of tests on three lamps. That curve does drop a certain amount, and the curve in Fig. B drops rather more, but perhaps the average curve obtained with the commercial lamp of to-day drops more than either. Still I would point out one fact with reference to judging the performance of the lamps by those which one sees burning in shops, namely that in the first part of the curve there is a very marked drop in candle-power from about 130 to 110. My experience is that there is always a drop corresponding to that, though not perhaps always so great, and sometimes a little greater. The result is that after the first 50 hours the light from a Nernst lamp seems to change a good deal in colour on account of this first drop. The light is a very white one at first and remains white during the whole life, but one notices a considerable difference in shade if two lamps, one new and one 50 hours old, are observed side by side. But after that drop the candle-power remains fairly steady, as shown by the curve, which is quite a typical one. When the curve drops Off sharply towards the end it is a sign that the lamp is about to fail. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Journal of the Society of Telegraph-Engineers and Electricians, 1885, Vol. 14 This is of great importance, as it is the only method a local me; the ordinary method of connecting to an electrometer being useless. This Peltier is quite independent of the efi'ect of contact-forces of the circuit. But the e.m.f. Does not account opposite. Hence.
