An infinitely long solid cylindrical conductor of radius R carries a free current density J(s) = Cs^3z distributed over its cross section.
The z axis is the long axis of the cylinder. The conductor has a permeability 'mu' which does not equal 'mu-0'. Outside the conductor is a vacuum.
A. Find H, B, M inside the conductor and discern between diamagnetic and paramagnetic materials.
B. Find H,B,M outside the conductor.
C. Sketch the situation for diamagnetic and paramagnetic materials.
The variables are provided as high (1) and low (0) levels for digital control. An alarm should be initiated whenever any of the following occur: a. Speed is low; both weight and loading rate are high.
An input signal of 10V at 0o is applied to a parallel RLC circuit with resistor R = 100 , inductive reactance XL = 200 , and capacitive reactance XC = 200 . All three components are connected in parallel to the source.
Build a 4-to-1 MUX using some tri-state buffers and two inverters(NOT gates). (Hint: you can build a 2-to-1 MUX using some tri-statebuffers and one inverter and then combine several 2-to-1 MUXes tobuild a 4-to-1 MUX.)
A perfect conductor joins two ends of a 100 ohm resistor and closed loop is in the region of uniform magnetic flux density B = 10*e^(-t/10) T. Neglecting the self-inductance of the loop, find and plot the voltage V(t)
What is the maximum power dissipated in the load when the Thévenin voltage is 17 V cos(37 rad/s t + 24°), the Thévenin impedance is 127 -j 182-ohm and the load impedance is 127 + j 182-ohm
name several methods for ISI mitigration. How does ISIdepend on the carrier frequancy, symbol rate, and movement ofsender/receiver what are the influences of ISI on TDM schemes
Fuel cell systems that also utilize the heat produced can achieve efficiencies approaching 80 percent , more than double of the gas-turbine based electruiical generation . Assume that 25 million houuseholds produce an average of 5 kw.
Plot accurately the gain and phase as functions of w with a matlab program you write. Attach plots and your own program. Note: Bode plots or any plots with logarithmic scale of either axis are NOT acceptable.
The switch of The switch of given Figure is closed at t = 0 s. How long is it until current reaches its steady value. Figure is closed at t = 0 s. How long is it until current reaches its steady value. An unknown circuit containing dc sources and re..
Any flip-flop type can be implemented from another type with suitable logic applied to the latter's inputs. Show how to implement a loadable D flip-flop starting with a T flip-flop.
Design by direct implementation the electronic circuits for equations as the following logic equations using any real 1, 2, or 3 input logic gates. Assume all signals are high true (positive logic) and do not simplify the equations.
A sinusoidal current is zero at t = - 625 s and increasing at a rate of 8000 A/s. The maximum amplitude of the current is 20 A. a) What is the frequency of i in radians per second
