Re: PTU EMFT Question Papers
Here I am providing you question papers of PTU B. Tech EE 5th Sem. Of Electromagnetic Field Theory, please have a look…. The question paper divided into three sections namely Section A, Section B and Section C. Section - A (10 x 2 =20) a) Mention the importance of a unit vector. b) State Faraday's law of electromagnetic induction. c) Write Laplace's equation in cylindrical coordinates. d) State normal boundary conditions. e) What are the conditions for field to be irrotational? f) Define Poynting vector. g) State the Stokes' theorem. What do you infer from it? r h)What is meant by homogeneous an,disotropic medium? i) Define propagation constant. j) State uniqueness theorem Section -B (4x5=20) Q2) State and prove the Gauss's theorem. Explain why it is called the diverg~ . theorem. Q3) Explain the concept of 'Displacement Current' . How is this current different from conduction current? Q4) Write Maxwell's equation in free space for the time varying fields both in differenti~l and integral form. Why these e(}uations are not completely symmetrical? Q5) Prove that in a travelling plane electromagnetic wave there is a definite ratio between the'amplitudes of E and H and find this ratio. Q6) Explain briefly the oblique incidence of wave on conductors. S~~tion - C (2 x 10 = 20) Q7) (a) Justify that the net Electric field within a conductor is always zero. (b) Derive the equation of continuity for time varying fields. Q8) Define uniform plane wave propagation. Discuss its properties. A uniform plane electromagnetic wave propagating in air is given by E =ix cos [wt - (2I1/A)Y] Derive by using the Maxwell's equations, the expression for the vector magnetic field. Q9) Write short notes on the following: (a) Magnetic vector potential. (b) Helmholtz equations PTU question paper of B. Tech EE 5th Sem. Of Electromagnetic Field Theory |
