Unformatted text preview: EE501  Assignment 3 1. Two rails each have a resistance of 2.2ohms/m. A bar moves to the right at a constant speed of 9m/s in a uniform magnetic field of 0.8T. Find I(t), 0<t<1s, if the bar is at x = 2m at t = 0 and a) A 0.3ohm resistor is present across the left end with the right end open circuited. b) 0.3ohm resistor is present across each end. 2. Let for the field a) Find w b) Determine displacement current c) Total magnetic flux passing through the rectangle defined by 0<x<1, y=0, 0<z<1, at t=0 3. Let the internal dimensions of a coaxial capacitor be a = 1.2cm, b = 4cm and l = 40cm. the homogeneous material inside the capacitor has parameters = 1e11 F/m, =1e5 H/m and σ = 1e5 S/m. If the electric field intensity is find a) J; b) The total conduction current I c through the capacitor; c) The total displacement current I d through the capacitor; d) The quality factor (I d / I c ) 4. A square loop of side l is oriented to lie in the xyplane such that its two sides are along the x and y...
