Abstract
Previous authors have brought forward evidence tending to show that a straight tungsten wire burning as an incandescent filament in a vacuum lamp fails by developing a hot spot at a place where the wire happened to be necked-down originally. It is shown here experimentally that in a gas-filled lamp, necking of a certain degree very probably does have this effect, at least if the filament is horizontal.Keywords
