-
First electric battery invented by Alessandro Volta. Volta proved that electricity could travel over wires.
-
-
Thomas Young gives his theory on newton's rings based on waves.
-
He explains the fringes of shadows by using the wave theory of light.
-
He shows the essential elements of Volta's pile.
-
David Brewster invents the kaleidoscope. First energy utility in US founded.
-
Michael Faraday begins electrical work by repeating Oersted's experiments. First electric motor is invented by Faraday.
-
He shows that the equations of Navier and Cauchy have wave solutions of two types: transverse and longitudinal. Mathematical physicists spend the next 50 years trying to invent an elastic aether for which the longitudinal waves are absent.
-
Joseph Henry independently discovers induced currents.
-
Michael Faraday discovers self inductance.
-
Michael Faraday discovers the idea of the dielectric constant
-
First industrial electrical motors.
