1. Classical Free Electron Theory and its Assumptions
The classical free electron theory explains the electrical behavior of metals by assuming that a metal consists of a lattice of positive ions surrounded by a gas of free electrons. These electrons move freely inside the metal and obey classical Newtonian mechanics. Electron–electron interactions are neglected and collisions occur only with fixed ions. The electrons follow Maxwell–Boltzmann statistics and an applied electric field causes a...
MEANING OF RESEARCH
•Research refers to a careful, well-defined (or redefined), objective, and systematic
method of search for knowledge, or formulation of a theory that is driven by
inquisitiveness for that which is unknown and useful on a particular aspect so as to make
an original contribution to expand the existing knowledge base.
•Research involves formulation of hypothesis or proposition of solutions, data analysis,
and deductions; and ascertaining whether the conclusions fit the hypothesis.
