1. What is the permittivity of free space? What are its units?
2. Describe the electric field due to a point charge.
3. How do you find the electric field intensity due to a continuous charge distribution?
4. How is current density defined? What are its units?
5. For a current flowing on a sheet, how would you define the current density at a point on the sheet? What are the units?
Determine for each of following 4 signals if it is bandlimited and, if yes, find the minimum sampling rate without causing aliasing. (a) x1(t) = cos(500pt) + sin(700pt); (b) x2(t) = sin2(50pt);
determine the following. (a) The line current (b) The value of the capacitor in uf per phase, is a wye-connected capacitor bank is used to correct the power factor to a 0.95 lagging power factor.
A temperature sensor has a static transfer function of 0.15mV/C and a time constant of 3.3s. If a step change of 22 degrees to 50 degrees C is applied at t=0, find the output voltages at .5s, 2.0s, 3.3s, and 9s. What is the indicated temperature a..
A solid metal cube has a spherical cavity at its center as shown in Fig. 22-28. At the center of the cavity there is a point charge Q = +8.00 µC. The metal cube carries a net charge q = -6.00 µC (not including Q).
a) Describe the components and variables of the biological control apparatus involved in walking toward an object that can be seen on the horizon b) Why is walking a closed-loop operation
Construct the RC differentiator. Set the channel 1 input coupling switch to dc. Next adjust the dc offset, amplitude, and frequency controls of the function generator to produce the input waveform.
The graph in Figure 5.8 shows the age distribution for AIDS deaths in the United States through 1995. Approximate the mean and standard deviation of this age distribution. How does the mean age compare to the approximate median age?
a resistance coil ab of 100 omega resistance is to be used as a potentiometer and is connected to a supply at 230 v.
The bellows, diaphragm, and Bourdon tube pressure sensors all exhibit second order time response. This means that a sudden change in pressure will cause an oscillation in the displacement and, therefore in the sensor output.
Desing a mod-16 asynchrous ripple up counter by using j-k flip-flops. You need to design a j-k flip flop first and use it as the component in mod-16 up counter design. Show both j-k flip-flop design implementation results .
write a program using the data type you declared to interactively accepts the above data into an array of five
Given a satellite altitude and desired illumination spot diameter on the earth surface, use MATLAB to determine the antenna aperture diameter and maximum gain to give the desired spot diameter.
