An electron is a subatomic particle commonly represented as e- or e. It posses negative polarity. Know the value of Electron like its mass, charge and spin and units.
The electron is perhaps the most fundamental carrier of electric charge. Unlike the proton which is made up of quarks, the electron is a type of particle that is known as a "lepton", which so far particle physics has not discovered anything else that makes it up....

It would not be an exaggeration to say that semiconductors have transformed human life over last 60 years. From computers to communications to internet and video games,semiconductor technology has expanded human experience in a way that is unique in history. In the late 1940s the invention of ...
What is the length of a box in which the minimum energy of an electron is 1.3 x 10−18 J? Energy of a Particle in a Box:A particle confined in a finite potential well can also be considered to be confined in a box. The particle thus have discrete energies...
The potential energy is the work required to move a positive charge in the presence of an electric field. This potential energy per unit test charge is defined as the voltage. The voltage is also known as the potential difference between the two points. The potential energy is one form of ...
