A device to set up electrical resonances in their brains, or something similar?

His later work involved electrical resonance, which he initially investigated for its potential use in an automatic telephone exchange.

Tesla did not invent the idea of electrical resonance.

By the 1890s electrical resonance was much more widely understood and had become a normal part of the engineer's toolkit.

The electrical resonance of tuned circuits in radios allow individual stations to be selected.

The water was subjected to an electrical resonance that dissociated it into its basic atomic make-up.

This song possesses a much faster tempo and the electrical resonance adds another dimension to the album.

They will not produce excessive voltage levels and are not susceptible to electrical resonances.

Nikola Tesla experimented with electrical resonance and studied various lighting systems.

Although electrical resonance had been investigated by researchers from a very early stage, it was at first not widely understood by electrical engineers.

Often guy cables have several insulators, placed to break up the cable into lengths unwanted electrical resonances in the guy.

Tuning is done by adjusting the length of an electrically long linear antenna to alter the electrical resonance of the antenna.

He believed that he had achieved Earth electrical resonance at Colorado Springs that, according to his theory, would produce electrical effects at any terrestrial distance.

Electrical resonance occurs in an electric circuit at a particular resonance frequency when the imaginary parts of impedances or admittances of circuit elements cancel each other.

Portions include sinusoidal alternating quantities such as peak values, instantaneous values, RMS average values, phase; electrical resonance, and quality factor for radio circuits.

From 1896 to 1906 he also gave an annual short course of instruction in electrical resonance at the Massachusetts Institute of Technology to graduating classes in physics and electrical engineering.

The final reference to "burning out" a machine was to emphasize the ability of such a system to transmit a large power given a proper impedance match, as can be obtained through electrical resonance.

Mechanical waves can be generated in a medium by subjecting an electromechanical element to an alternating electric field having a frequency which induces mechanical resonance and is below any electrical resonance frequency.

But one of the people who was fascinated with alternating current, and all the amazing effects of electrical resonance, was the eccentric genius and engineer whose picture we saw at the beginning - Nikola Tesla.(1856-1943).

It was his 1927 paper in Archiv für Elektrotechnik that Ernest Lawrence read in 1929, which gave him the idea for electrical resonance particle acceleration of protons, resulting in the cyclotron.

This situation was not to last for long; electrical resonance had been known to science for some time before this, and it was not long before engineers started to produce all-electric designs for filters.

Consequently, the much more familiar concept of acoustic resonance (which in turn, can be explained in terms of the even more familiar mechanical resonance) found its way into filter design ahead of electrical resonance.

Trying to solve a problem with the failure in the electrical wire insulation on steel ships (which turned out to be a problem with electrical resonance) led him to further explore oscillations of high frequency electrical currents.

However, a very early example (1870s) of acoustic filtering was the "harmonic telegraph", which arose precisely because electrical resonance was poorly understood but mechanical resonance (in particular, acoustic resonance) was very familiar to engineers.

The "fuel cell", which he claimed was subjected to an electrical resonance, would split the water mist into hydrogen and oxygen gas, which would then be combusted back into water vapour in a conventional internal combustion engine to produce net energy.
