Given a 4.0-nC charge on a 1.0 meter length of an inner cylindricalshell of radius a = 0.060 m, a -4.0-nC charge on a 1.0 meter lengthof an outer cylindrical shell of radius b = 0.077 m, & anεr = 9.0 dielectric in between the shells,(a) determine the potential difference between the cylindrical shells, &(b) determine the capacitance per meter length between the shells.
A transmission line has the following per-unit-length parameters: L = 0.5 H/m, C = 200 pF/m, R = 4.0 /m, and G = 0.02 S/m. Calculate the propagation constant and characteristic impedance of this line at 800 MHz. If the line is 30 cm long
The current density in a cylindrical conductor of radius R = 43.1 cm, varies as J(r) = J0r/R (in the region from zero to R), where J0 = 0.417 C/m2. a) Find the magnitude of the magnetic field at r = 21.55 cm.
An OpAMP has a unity gain frequency (ft) of 10MHz and a slew rate of 10V/us and AVoc = 120dB at DC (f=0).Assume VCC = -VEE = 15 Volts. a. Approximate the cutoff frequency of the OPAMP itself.
After a package is ejected from the plane, how long will it take for it to reach sea level from the time it is ejected Assume that the package, like the plane, has an initial velocity of 200 mph in the horizontal direction.
Plot how this absorbed power varies with signal strength W12, and discuss the behavior especially at very small and very large W12. Where does the absorbed power go? -and how does it get there?
The source-free circuit depricted in Fig. 9.1 is constructed using a 10mH inductor, a 1mF capacitor, and a 1.5k ohms resistor. a) Calculate alpha ( neperfrequency or exponential damping coefficient), omega-sub-delta (natural resonance frequency)
A Polyester capacitor with a leakage specification of 5x109 O -µ F is used in a circuit. The voltage across this capacitor is 100 volts D.C. and the capacitance is 0.1µ F find the leakage current.
Use Matlab to find out what function in time x(t) resulted in the Fourier Series Coefficients Xn = j/(2*p*n) for n?0 and X0=0. You can accomplish this by synthesizing the signal from sufficient frequency components.
Design a circuit that will display the decimal numbers that are less than 60 by using two 7-segment displays. The number 60 should be displayed as 00. Use the least amount of IC's as possible.
Three single-phase transformer are used to form a three-phase transformer bank rated 13.8kV(delta)/120kV(wye). One side is connected to a three-phase load of 12 MVA at 0.8 power factor lagging. Determine the turns ratio of each transformer
Find an expression for the scalar electric potential at any point on the axis of the ring. Indicate clearly your coordinate system and its geometry. Check the limiting case as the field point recedes to infinity.
