It has generally been assumed that to produce a maximum voltage on the secondary terminals the resonance relation L₁C₁=L₂C₂, as proposed by Drude, was sufficient, these symbols referring to the...

Our issue of the 25th of May contained an abstract of a Paper by Prof. Galileo Ferraris describing a method of producing a revolving resultant magnetic field by means of a pair of coils with their...

Mr. Nikola Tesla's lecture , delivered in February last before the Franklin Institute at Philadelphia, and before the National Electric Light Association in March, has now been published in the...

In introducing conducting wires on different metals into his resonator Hertz asserted that neither the resistance nor the magnetic properties of the metal involved a sensible change in the length of...

It is hard to imagine what a dynamo or an arc lamp would be like if the air, instead of being an insulator, were a conductor; but a moment's thought is enough to show how important the passive...

Although the theory of the Tesla motor is now so widely known - though doubtless better known than understood - yet the practical construction of the apparatus has not yet been explained. The...

The following is an abstract of a Paper of which an advance proof was kindly sent us by Prof. Elihu Thomson:- In connection with an experimental investigation of the properties of alternating currents...

In his address on "Pioneers' Day" at the recent meeting of the National Electric Association at Providence (R.I.), Prof. Elihu Thomson gave the following interesting account of his early experiences:...

TO THE EDITOR OF THE ELECTRICIAN. Sir: In The Electrician for July 17th there is a description of some experiments made by Mr. Nikola Tesla, which are somewhat similar in character to those shown by...

The beautiful and suggestive experiments on the electric discharge in vacuum tubes, shown by Prof. J. J. Thomson on the occasion of the visit of the Physical Society to Cambridge, in May, have excited...
