When a charged condenser is discharged through a circuit possessing high induction and low resistance electrical oscillations are produced, the frequency of these being given by 2!$ \pi !$ √KL, where...

A vacuum tube, the inner portion of which has fused to it crystals of tungstate of calcium when exhausted to the X-ray stage, gives out scarcely any of the rays; on the other hand, the tubes shine...

Most members of the electrical profession associate the name of Nikola Tesla with high-frequency and high-potential currents, and few are acquainted with the fact that he has also invented several...

One of the most noteworthy developments in the domain of alternate current working is the prominence which has been given within a comparatively short time to the condenser and its action in relation...

Pending the publication of the full report of Mr. Tesla's lecture before the American Institute of Electrical Engineers , we give this week the essential principles embodied in a new system of...

In his lecture delivered before the American Institute of Electrical Engineers , 1 Mr. Nikola Tesla dwelt at length upon the fact that the direct application of electro-magnetic waves to the...

While the interest in all the papers of the annual meeting of the American Institute of Electrical Engineers was sustained throughout the sessions, there can be no question that most interest centred...

The Wednesday evening session of the American Institute of Electrical Engineers was held in Prof. Dwight's room, Columbia College, and will long be remembered by those present, not only on account of...

The interesting account of the novel experiments given by Mr. Nikola Tesla in the Electrical World of Feb. 21, 1891, and relating to the phenomena of alternating currents of very high frequency, lead...

During the third and the last of this series of Cantor lectures at the Society of Arts, Mr. Gisbert Kapp dealt very fully with the probabilities of transmission of power electrically by means of...
