A coaxial air line has an inner conductor diameter of 2mm and the inner diameter of the outer conductor is 4.6mm. A voltage of 1 V is applied to the inner conductor.
(a) Determine the surface charge densities on the inner conductor and the inner surface of the outer conductor.
(b) What is the potential at a point midway between the conductors?
(c) What is the resistance of this coaxial line per meter at dc, assuming that the outer is 0.5mm thick, and both conductors are made of copper conductivity = 5:8 107 S/m.
(d) What is the capacitance per meter of this coaxial line?
(e) What is the impedance of this coaxial line?
A parallel circuit consists of a source and 15 ohm and 30 ohm resistors. The resistor of 15ohm draws a current of 8A. a) Find the current out of the current source. b) Find the current through the 30 ohm resistor.
Vs=310 V (Vrms=219 V) at the input of bridge rectifier Need LC filter at the output of bridge which can provide 240 V +-10V DC, with 2 A constant current. find method to find appropriate values of LC which can provide these specification.
where the assigned loop current leaves the voltage source. If current leaves the voltage source at its positive terminal, the voltage would be positive and if it leaves the voltage source at its negative terminal,the voltage would be negative.
Two points are given P1 (1,0,1) and P2 (6,-3,0) Calculate: a) The scalar components of the vector pointing from P1 to P2. b)The scalar components of the vector pointing from the origin to P1. c) The magnitude of the vector pointing from P1 to P2 ..
A bar phantom is imaged by an LSI system which is modeled as an ideal moving average system. The PSF of the system is h(x,y) = rect(x/delta, y/delta) (a) If bar separation of the bar phantom is f what is the output of the imaging system
Given an object with a mass of 55 lbm, who starts at rest but experiences a constant horiz. force due to resultant force applied for 10 seconds. The work of the resultant force is 7,782 lbf*ft.
A power company supplies 75 kW to an industrial load. The load draws 120 Arms from the transmission line. If the load voltage is 440 Vrms and the load power factor is 0.8 lagging, find the losses in the transmission line.
During four consecutive clock pulses, a sequence of four values of the x signal is applied. Derive a state table for the FSM that produces z = 1 when it detects that either the sequence 1001 or 0111 has been applied; otherwise, z = 0. After the fo..
A box of mass 20kg is slid down a ramp inclined at 20 degree with an initial speed of 5 m/s. If the box stops after 10 m, what was the coefficient of kinetic friction between the box and the ramp
Do either or both of the reasons you gave in part (a) above also apply to a point to point voice link using frequency modulation? c. Which parameter of an FM transmission determines whether it is wideband or narrow band?
