A complex electric field vector is given by E¯(¯r) =A/k * (ˆxk(z) - zˆk(x))e^-j(k(x)x+k(z)z) , where A is a complex number and k = µ is the real magnitude of the wave vector ¯k. a. What is the wave vector ¯k? b. What is the magnetic field H¯(¯r)? c. What is the time average Poynting power < S¯(¯r) >=(1/2)Re{E¯ × H¯*}? d. What is the time domain electric field E¯(¯r, t)?
What is the purpose of core in hollow solder wire What is tinning, and why is it important Why is safety so important when soldering Why has lead-free solder replaced lead-based solder
A PWM is used in 8-bit mode to produce a signal with a 1 msec period and 60% duty cycle. Determine the value required for any pre-scaling, and the values for the period, and duty cycle registers. The E-clock is 24 MHz.
A magnetic pickup coil is being used to make measurements which areproportional to the time derivative of the magnetic flux density, dB/dt. You wishto integrate this signal to get the magnetic flux density, B.
Consider a three-phase distribution feeder with line reactance of10 ohm supplying a three-phase Y-connected load of 200 kVA at power factor of 0.85 lagging.
Use MATLAB to compute the inverse Laplace transform of X(s)=(s^2+2s+1)/(s(s+1)(s^2+10s+50)) and determine the value of x(t) in the steady state. How would you be able to obtain this value without computing the inverse? Explain.
Write a sequence of instructions to initialize and run the timer to geneate an 800 baud rate clock. what would be the baud rate if the intial value of the timer was set to 9AH
Write a main program to call a procedure that converts the Fahrenheit temperature value stored in the location labeled TdegF to its Celsius equivalent. The range of temperatures is 32°F to 212°F. The procedure stores the converted temperature
A single-phase overhead transmission line consists of two solid aluminum conductors having a radius of 2.5 cm, with a spacing 3.6m between centers. a)Determine the total line inductance in mH/m.
An unbalanced Wheatstone bridge circuit has resistance arms of 400, 40, 602, and 6000-ohm taken counterclockwise around the bridge. The galvanometer has a resistance of Rg=110-ohm and is connected between the junction of the 40 and 602-ohm resisto..
The dimmer knob is adjusted such that it applies voltage to the load during the initial 28 % of each half cycle of the standard 120V/60 Hz AC voltage. Find the real (average) power dissipated on the load in watts.
With a 500hp shunt wound DC motor, at 1800rpm, 500Vdc, FLA is 800Adc, Ra is 0.025 and Rf is 400. What would Va need to be if you wanted the motor to operate at 1000rpm at rated torque. Keeping the field current constant.
A new 24-bit processor is being designed for operation in a cell phone (you can assume the word-size is 24 bits). Suppose the following memory values are being stored in memory that is organized where each location is 8-bits wide (byte addressable..
