About a year and a half ago while engaged in the study of alternate currents of short period, it occurred to me that such currents could be obtained by rotating charged surfaces in close proximity to...

Sir — In your issue of March 6 I find the passage: “Mr. Kapp described the position as it exists. He showed how Ferraris first of all pointed out the right way to get an alternating-current motor that...

I cannot pass without comment the note of Prof. Thomson in your issue of April 1, although I dislike very much to engage in a prolonged controversy. I would gladly let Prof. Thomson have the last word...

Fifteen or sixteen years ago, when I was pursuing my course at the college, I was told by an eminent physicist that a motor could not be operated without the use of brushes and commutators, or...

In The Electrical Engineer issue of 11th inst., I find a note of Prof. Elihu Thomson relating to some of my experiments with alternating currents of very high frequency. Prof. Thomson calls the...

Alternate current machines of high frequency; curious experiments with Geissler tubes and lamps; an exploded notion; noiseless alternating arcs; constant current and constant potential; interested...

I hope you will allow me the privilege to say in the columns of your esteemed journal a few words in regard to an article which appeared in Industries of August 22, to which my attention has been...

Some time ago Mr. Swinburne advanced certain views on transformers which have elicited some comment. In The Electrical Engineer of Sept. 10 . there are brought out further arguments on behalf of his...

In your issue of April 2, in referring to certain remarks made by me at the recent meeting of the American Institute of Electrical Engineers on the subject of hysteresis you make the statement: “It is...

To the Editor of The Electrical World: SIR: About a year ago I had the pleasure of bringing before the American Institute of Electrical Engineers the results of some of my work on alternate current...
