However, most of them failed as none of them were able to create a perfect vacuum.
#J.j.thomson cathode ray experiment series
After carrying out a series of experiments with – solids, liquids, and gases, scientists took one step further to drive electricity through a vacuum. They proved that the electricity or the electric current can flow through any substance – solid, liquid or gas if enough driving force or electric potential exists.
The magnitude of the electric current flowing through a substance is directly proportional to the electric potential applied across it. The electric potential is a driving force that results in the flow of current through a substance due to the difference in concentration of charges at two ends of it. Scientists in the early nineteenth century were aware of electricity and the effect of electric potential. Who discovered electrons CATHODE RAY EXPERIMENT To know about the basic structure of an atom, click here This led to the discovery of the nucleus and other subatomic particles – protons and neutrons. Thomson discovered electrons, the race began among other scientists to uncover the basic structure of an atom. In his quest to study properties of cathode rays, he discovered that atoms contain negatively charged subatomic particles – ‘electrons’. But things changed after the discovery made by an English scientist named J.J. Thomson, the one who discovered electronsįor a long period in history, scientists were of opinion that atoms could not be broken further.
