The practical significance of these advantages were apparently missed by many lamp developers including Sawyer & Man, even years after Edison‘s patent issued, as they persisted in futile attempts to solve problems inherent only to thick carbon incandescent rods of low resistance that drew high currents and incurred high rate of erosion.26 A few years after Edison‘s patent issued Sawyer continued to insist that the resistance of the carbon… [read post]
