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
For higher current rating application, resistance wires with extremely large cross sections are required. The necessary large cross sections are produced in the form of resistance
Refracting telescopes, if uncorrected, suffer from chromatic aberration. Chromatic aberration occurs because: a) red light is focused more strongly than blue light b)
When current is passed by a junction of two dissimilar solids, the temperature is either evolved or absorbed at the node. This effect is known as Peltier effect
