Bohr given a model for hydrogen molecule which is also applicable for some lighter atoms in which a one electron revolves around a stationary nucleus of positive charge Ze (known as hydrogen like atom)
Bohr's model is based on the following postulates.
(i) The electron can revolve only in particular discrete non-radiating orbits, named stationary orbits, for which total angular momentum of the revolving electrons is an integral multiple of
MOVEMENT OF CHARGE: Although electric current is referred to as the flow of electrons through a conductor, it should be noted that more exactly, any movement of electric charge
The energy possessed by a object by virtue of its position or its configuration is called its potential energy. Concept of potential energy is valid only in conservative field.
Chemical changes during: Discharging: The current will flow from positive to negative plate in the external circuit. As current now enters by negative plate, the negative
