Difference between bipolar junction transistor (BJT) and field effect transistor (FET)
BJT and FET are electronic devices. The basic difference between BJT and FET is that the bipolar junction transistor is the bipolar and current control device, while FET (field effect transistor) is the unijunction transistor. It is a voltage control…

What is difference between excitation and ionization potentials?
Excitation potential The potential required to lift an electron from the ground state to some higher state is called excitation potential. Or If the energy supplied to an electron is such that the electron is lifted from its ground state…
