In a heavily doped PN junction, when the depletion layer is extremely thin, carriers cannot accelerate enough to cause ionization. Hence in... View Article
Ionization energy is the minimum energy required to remove one electron from the atom or ion in its ground state. Binding energy is the least... View Article
Lanthanum is grouped in the F block since it has partially filled f-orbitals. F-orbitals of electron shells are filled with n - 2 electrons. To... View Article
AC voltage is preferred over DC voltage because it is economical and less complicated. AC voltage is more efficient than DC since minimum energy... View Article
Two characteristics that define a system at equilibrium are: The rates of forward and reverse reactions are equal. All the reactants and... View Article
