[N083001], Technical Note, Samuel Dimmick Mott, December 1879

Editor's Notes

"Notes and mechanical movements. Things to e looked-up and remembered both electrtical and otherwise." Fr 704 begins preliminary esetimate of the cost of lighting 10,000 Edison electric lamps from a central station each lamp giving a light equal to 16 candles, or taking the place of a gas jet consuming 5 cu ft per hour. Estimates of capital investment----identical to Mott ests from Oct? Depreciation; coal; summary. Power---estimate can sell 40 hp during the day for power. Mr. Edison's analogy for the intensity of a current and the electromotive force of a current is that a belt moving at a certain velocity is as the emf and intensity is varied as its width." Drawings of parallel, series circuit arrangements; wheatstone bridge.
