The free electron theory of metals was first proposed by Drude and later improved by Lorentz. The main postulates of this theory are
1. All metal contain, adequate number of valence electron forming an electron gas which is free to move throughout the volume of the metal. A metal can be regarded as an array of positive ions permeated by a gas of free electrons.
2. The electron velocities in metals obey the classical Maxwell-Boltzmann distribution of velocities.
3. In the absence of an electric field the electrons move in random directions, making collisions from time to time with positive ions. Which are fixed in lattice.
4. The free electrons in the electron gas wander freely in the metal without any mutual interation. 6. When an electric field is applied to the free electrons are accelerated. They move in opposite direction to the electric field while maintaining their random motion.
NPN BJT with forward-biased: An NPN transistor can be referred as two diodes along with a shared anode. In common operation, the base-emitter junction is forward biased and th

(a) Consider a 5-µH inductor to which a current source i(t) is attached, as shown in Figure (b). Sketch the inductor voltage and stored energy as a function of time. (b) Let a v
To have the same value of P e , show that E b /N 0 in a coherent-ASK system has to be twice that in a coherent PSK system.
Q. Illustrate Inductance with example? An ideal inductor is also an energy-storage circuit element (with no loss associated with it) like a capacitor, but representing the magn
