What is Electronic Theory of Electric Charging ? Notes with Video explanation -
According to Electronic Theory of Electric Charging "A body can be charged by the transfer of electrons". The process of developing charge in a body is called electrification. Matter is made up of atoms, Each atom has positive as well as negative charges. Positive charge (protons) is present in the nucleus of the atoms and negative charge (Electrons) revolves around the nucleus. In an atom, the number of positivity charged (protons) must be equal to the number of negatively charged electrons. Hence , the net charge on an atoms is zero. Therefore , matter is electrically neutral. The atoms of different substances hold the electrons in their outermost orbits with different strength. The maximum energy required to remove an electron from an atom is called work function. Smaller the work function easier will be the removal of electron and vice-versa. Metals have a low value of work function and that for non-metal is high. When two Bodies are rubbed together , electrons in ...
