It matter what kind of electronics. Because some was made in different times and years.

But the history of this discovery is more long and complicate.

Who invented the atoms have protons and electrons?
albert Einstein
Which inventor made electrons?
A electron is one of the 3 things you need to complet a ATOM. getting back to the subject , so a electron is a thing in the ELECTRON CLOUD.
Who is jj tompson?
He is the one who discovered electrons , isotopes and invented the mass spectrometer .
What kind of father in science jj Thomson?
He discovered electrons, isotopes, and invented the mass spectrometer.
When were exrays invented?
X-rays were invented in 1895 by German physicist Whilhen Conrad-Rontgen. He discovered the fluorescent screen glowed while experimenting with electrons in his lab.
Who invented the negatively charged particle electron?
J.J. Thomson discovered the negatively charged particles, electrons in 1897.
Who invented the scanning tunneling microscope?
a scanning tunneling microscope measures electrons that leak, or 'tunnel', fromthe surface of specimen
The emission of electrons in high-vacuum tubes is caused by?
The heating by the filament causes the electrons to "boil off". Edison noted this phenomena and it was later picked up by Fleming who used a "grid" which could control the flow of the electrons by introducting a repelling field between the Cathode (heated element that emitted the electrons) and the anode that attracted the free electrons, thus the "Fleming Valve" was invented (the vacuum tube.
Who invented the Bohr model and what does it look like?
Niels Bohr created this model; electrons move around the positive atomic nucleus.
Who discovered negative charge?
J.J Thompson in 1897 demonstrated that cathode rays are composed of tiny, negatively charged subatomic particles called electrons.
How do electrons travel though a cuircuit?
Electrons jump from one metal conductor ion's valence shell (the outer most space for electrons around atoms) to another at a rate defined by the voltage and current supplied. The source for theses forces may be a chemical reaction pulling ions in different directions or a magnet pulling the electrons in one direction. An interesting fact, electricity doesn't move at the speed of light, so they invented fiber optic cables.
Which subatomic particle determines reactivity?
Electrons, for chemical reactions
