Item

Abstract

"Results from book 103" CP, ohms, duration of c. dozen bamboo lamps. Notes: "a low resistance lamp with high economy lasts well. A low resistance lamp with low economy shows some fault in cutting. The life of a lamp depends entirely on the weakest spot, and the lamp always breaks at the spot which shows at low red the brightest. The blue in a lamp depends on the highest temperature of any part of the carbon and on internal arcs."
