| Twice as efficient as carbon filament lamps, Nernst lamps were briefly popular until overtaken by lamps using metal filaments. |
| This was Professor Nernst, the inventor of a well-known electric lamp and a man who had always violently hated the British. |
| The calibration yields a value for the standard electrode potential, E0, and a slope factor, f, so that the Nernst equation in the form. |
| Ideally, electrode potential, E, follows the Nernst equation, which, for the hydrogen ion can be written as. |
| The Nernst lamp, therefore, consists of a slender rod of the mixed oxides attached to platinum wires by an oxide paste. |
| No advantage is obtained by over-running a Nernst lamp, this only shortening its life without increasing the light. |
