This was the second attempt made by Professor Trowbridge to obtain the desired effect with a Crooke's tube. The first attempt, made a few minutes before, was partly successful. The ordinary sixty-volt alternating current used for lighting the building was sent through the primary of an ordinary coil. The resistance of the primary of this coil is one-tenth of an ohm, and of the secondary 6000 ohms. The current through the primary was not stronger than 15 ampheres. The current from the secondary of the first coil was sent through the primary of 25 turns...
...electrical department of the L. S. S. has been fitted with a Thompson-Houston 500 volt motor and a complete outlay of shop machinery, including 2 machine lathes, 2 speed lathes, drill press and milling machinery...
...commonly transmitted in this way with an efficiency of 74 per cent. of the power applied. Since the current always equals the pressure divided by the resistance and a man's resistance is about 2000 ohms, he cannot take more than a quarter an ampere from the 500 volt current of the street railway, whereas 10 amperes are necessary to kill. Interesting and convincing statistics were cited to prove the number of deaths from electricity almost nothing compared with those from all other violent causes. Figures also show the marvel louse increase of electrical railways and the small danger...
