Electric Arc

Klappentext Originally published in 1902, this comprehensive exploration of the electric arc represents the cutting-edge research of electrical engineer Hertha Ayrton. Zusammenfassung Although denied membership of the Royal Society, electrical engineer and suffragist Hertha Ayrton (1854–1923) undertook a vast range of scientific work, from the study of sand bars to the development of anti-aircraft lights. First published in 1902, this book is her comprehensive and illustrated study of electric arcs. Inhaltsverzeichnis 1. The appearance of the arc; 2. A short history of the arc; 3. 'Striking' the arc and sudden variations of current; 4. Curves for PD and current with constant length of arc, and for PD and length of arc with constant current; 5. Area of crater and crater ratios - variation of PD with diameters of cored carbons - constant current-resistance curves - constant PD curves; 6. The equation for PD, current, and length of arc, with solid carbons, and its application to the results of earlier experimenters; 7. The PD between each carbon and the arc, and the fall of potential through the arc; 8. Relations between EMF of generator, resistance in series with arc, PD, current and length of arc with solid carbons; 9. The power efficiency of the arc and the resistance needed in series with it; 10. Hissing arcs; 11. The light and luminous efficiency of the arc; 12. The mechanism of the arc - its true resistance - has it a large back EMF? The reason for the different effects of solid and cored carbons; Appendix.
