(b) : Given, A yi 2x j = − + ɵ ɵ Magnetic Induction B A = ∇× ɵ i j k d d d B dx dy dz y 2x 0 = − ɵ ɵ ( ) ( ) ɵ B i 0 j 0 k 2 1 = − + + ( ) ɵ ɵ B 3k = 2. F.E.T. is:/F.E.T. nw: (a) Current controlled device/Oeeje efveÙebef$ele Ùeb$e (b) Power controlled device/Meefòeâ (heeJej) efveÙebef$ele Ùeb$e (c) Voltage controlled device/efJeYeJeevlej efveÙebef$ele Ùeb$e (d) Resistance controlled device/ØeeflejesOe efveÙebef$ele Ùeb$e Ans. (c) : F.E.T. is a voltage controle device. A field-Effect transistor (FET) is a three-terminal semiconductor device that controle the flow of current using an electric field applied to one of its terminal and acting as voltage controlled device. 3. The average energy of Planck's oscillator of frequency v at an obsolute temperature T is: T leehe hej v DeeJe=efòe kesâ hueebkeâ oesefue$e keâer Deewmele Tpee& nesleer nw– (a) hv (b) nhv (c) hv/kT hv e 1       − (d) kT Ans. (c) : Average energy of plank oscillator it is total Energy (E) of oscillator and number of an oscillator (N). it is given by Eavg h 1 KT h e ν − ν = Where h = Plank constant ν = Frequency of oscillation K = Boltz man constant T = Absolute temperature 4. Fermi level for extrinsic semiconductor depends on: yee¢e (Skeämš^sveefpekeâ) DeOe&Ûeeuekeâ kesâ efueS Heâceea mlej efveYe&j keâjlee nw– (a) Donor element/oelee lelJe hej (b) Impurity concentration/DeMegælee meevõlee hej (c) Temperature/leehe hej (d) All above/GheÙeg&òeâ meYeer hej Ans. (d) : The Fermi level for extrinsic semiconductor depends on the donor element concentration of impurity and temperature Hence it depend upon all of these. 5.
