1. A 250 m, 2 wire D.C. distributor fed from one end is located uniformly at the rate of 1.6 A/metre. The resistance of each conductor is 0.0002 ohms per metre. Find the voltage necessary at feed point to maintain 250 V
i) At the far endii) At, the mid-point of the distributor
2) Derive an expression for the power loss in a uniformly loaded distributor fed at one end.
A 10 micro-Farad capacitor C1 is charged with 150 micro-Coulombs. An uncharged 15 micro-Farad capacitor, C2, is connected in parallel to C1. What is the resulting charge distribution, Q1 and Q2, on each respective capacitor
How can you design a high gain (at least 20dB) operational amplifier with only pmos transistors In most designs, they include both nmos and pmos transistors. Is it possible to substitute the pmos for the nmos
Coopetition often requires firms to communicate openly. How is this different from collusion? How can antitrust enforcers distinguish between coopetition and collusion?
Sketch a graph of the drain-source current, IDS, as a function of drain-source voltage, VDS, for an enhancement-mode NMOS transistor with a threshold voltage of 1 V. On the same graph indicate how this curve would be shifted for a depletion-mode N..
A DC motor, fed trough a four-quadrant chopper, works as a motor in thethird quadrant (reverse motion). The main data are Vo =120V, Ra = 0.5-ohm, La = 2.5mH, rated currentIan = 20A; rated speed nn = 3000rpm; separate excitation.
A thin slab of magnetic material is inserted next to the z = 0 wall of the rectangular cavity shown below. If the cavity is operating in the TE101 mode, derive a perturbational expression for the change in resonant frequency caused by the magnetic..
For a certain source-free parallel RLC circuit, R=1k-ohm, C=3uF and L is such that the circuit response is overdamped. Write an equation for the voltage across the resistor if it is known that v(0-) = 9V and dv/dt|t=0+= 2 V/s
A 1 V battery is connected across a series combination of a 2 k-ohm resistor and a forward-biased diode. Determine iD and vD for the diode using: (i) the ideal diode model; (ii) the constant drop model with vD = 0.7 V
Design a 1 dB equal-ripple band pass filter meeting these specifications using cap acitively coupled short-circuited shunt stub resonators. Assume an impedance of 50 .
If a cache being simulated were allowed to have a block size of 4 bytes, what optimization would be possible for blocks of that size that is not possible for block sizes 8 bytes and above
A ‘c-core' inductor has a total air-gap length of 3 mm and a cross-sectional area of 100 cm2. Two coils are wound on the core - one of 500-turns and another of 250-turns. Assuming the iron reluctance, fringing flux and leakage flux to be negligibl..
