Paperback. Etat : New. Print on Demand. This book, a thorough exploration of gas-filled lamps, delves into the new variables and photometric difficulties encountered in their use. The author, a renowned scientist at the Bureau of Standards, presents a systematic study of these variables, determining the relationship between voltage, current, speed, and candlepower when the lamp is rotated. This study led to the discovery of a unique phenomenon: at constant voltage, current and candlepower change in opposite directions when the lamp is rotating. The author further explains the cause of this variation, attributing it to changes in convection currents within the bulb, which in turn affects the temperature distribution and resistance of the lamp. Through careful experimentation, the author establishes a practical method for accurately measuring mean horizontal candlepower in gas-filled lamps, free from the errors caused by rotation. This method, along with the author's in-depth analysis of the underlying principles, enhances our understanding of gas-filled lamps and aids in their precise photometry. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781334318313_0
