State advantages of field effect transistors over Bipolar junction transistors

-

 (I) FETs are voltage controlled devices while bipolar junction transistors are current controlled devices

(II) FETs are less affected by radiation compared to BJTs

(III) The noise produced by FETs is lower compared to that produced by BJTs.

(IV) FETs are easier to fabricate compared to BJTs

(v) FETs has high input impedance compared to BJTs.

Explain Rutherford atomic model

-
 In his study on atoms ,Rutherford proposed Rutherford atomic model( Rutherford planetary model of an atom). The following are the salient features his model: (I) Every atom consist of tiny central core called nucleus which is entirely positively charged and it is a zone in which almost whole mass of the atom is concentrated. (II) Most of an atom is empty space (III) In free space around the nucleus there are electrons which move in orbits just like the planets around the sun and the centripetal force  needed for orbital motion of electrons is provided by electrostatic forces due to positively charged nucleus. (III) An atom as a whole is electrically neutral hence the total posively charge of the nucleus is exactly equal to total negative charge of all the electrons orbiting in an atom

Electron released from the cathode CRT is accelerated to the anode by accelerating potential of 2kV in time 0.25 microseconds. Taking the mass of the electron m = 9.1 x 10^-31kg and electron charge e = 1.6 x 10^-19C .Determine:

 (I) Velocity of the electrons Soln Velocity of electrons V = {√(2eEa)/(m)}      = {√ (2 x 1.6 x10^-19 x 2000)/(9.1 x 10-31)}       = 26519741.77 m/s (II) Acceleration of the electron Soln   Acceleration = change in velocity/time                 = (26519741.77 - 0)/(0.26x 10-6)                  = 1.01999 x 10^14 m/s^2 (III) Loss in potential energy     Loss in potential energy P.E = eEa                = (1.6 x10^-19) x ( 2000)                 = 3.2 x 10^-16 Joules (III) Gain in Kinetic energy       K.E = 1/2(m x V^2)      = 1/2( 9.1 x 10^-31 x 26519741.77^2)       = 3.2 x 10^-16 Joules
