1. Discuss the physical phenomena associated with each of the elements in the transmissionline equivalent circuit.
2. What is a transverse electromagnetic wave?
3. What is a field map? Describe the procedure for drawing the field map for a transmission line of arbitrary cross section.
a. Design a 3 bit combinational circuit 2's complimenter. (the circuit generates the 2's compliment of the input 3-bit binary number). [Show all work leading to the circuit implementation]
For a PMAC (permanent-magnet ac) machine, what would happen if the supplied frequency is not same with the rotating frequency of the rotor
Find the number of poles required, when the frequency is 50Hz and speed of the induction motor is 500 rpm?
we will weigh objects by a strain gauge or r 120omega gf 2.02 mounted on copper column of 6-in. diameter. find the
a. Implement both functions with one 3:8 decoder and logic gates. b. Implement both functions with one or more 8X1 muxes (and logic gates if needed) c. Implement both functions with 2X4 decoders and logic gates.
Implement the following function with a 4-to-1-line multiplexer Draw the truth table and the corresponding block diagramfor the MUX F(x,y, z) = f(1, 2, 6,7)
A 10 kW, 220 V, dc shunt motor has field and armature reistance of 110 ohms and .20 ohms, respectively. At no-load the motor runs at 1200 rpm and has an armature current of 5 A.
Compare the field at the center of a Helmholtz coil pair and at the center of a solenoid, if both use the same total length of wire and carry the same current.Take the solenoid length equal to the spacing between the Helmholtz coils
Consider the battery-charging circuit shown in Figure, in which vs(t) = 20 sin(200 πt),R = 80Ω ,VB = 12V, and the diode is ideal. a. Sketch the current i(t) to scale versus time. b. Determine the average charging current for the battery.
Distribution systems are normally operated as radial networks and a simple iterative procedure can be used to solve load flows in them. One of the common methods used is the forward and backward method. The procedure used in this method is?
Each window and door has a switch attached such that the contacts close when a door or window opens. Draw a ladder logic diagram that will turn on a light if one or more windows are open or if both doors are open.
Consider the waveform equation: a. What is the frequency of the waveform (in Hz) b. What is the voltage Vx at a time t = 1.5 ms c. What is the voltage Vx at a time t = 3 ms d. What is the voltage Vx at a time t = 4.5 ms
