(a) Consider a cylindrical conductor with radius a suspended inparallel over a conducting ground plane by a distance d in a medium with permittivity and conductivity. Calculate the capacitance per unit length between the two. You may assume that the distance dis much greater than the wire radius a. (d » a)(b) Consider two parallel cylindrical conductors with radius aseparated by distance 2d. Calculate the capacitance per unit lengthbetween the two. You may assume that the distance d is much greaterthan the wire radius a. (d » a)
A 15-kVA, 8000/230-V distribution transformer has an impedance referred to the primary of 80+j300 ohm. The components of the excitation branch referred to the primary side are Rc= 350k ohm and Xm=70k ohm.
Given a complete sequential program without any branches (no GOTO and CALL statements) that consists of 12813 instructions and a PIC microcontroller that is connected to a 2.0 MHz external clock/oscillator
A particular inverting amplifier with nominal gain of -100 V/V uses an imperfect op amp in conjunction with 100-k-ohm and 10-M-ohm resistors. The output voltage is found to be +9.31 V when measured with the input open and +9.09 V with the input groun..
A three-phase, wye-connected induction motor is supplied by a three-phase and foursin system with line-to-line voltage of 220V and the impedance of the motor is 6.3+j3.05Ohm per phase.
A person shuffling across a dry carpet can be approximately modeled as a charged 100-pF capacitance with one end grounded. If the person touches a grounded metallic object such as a water faucet, the capacitance is discharged
Determine the HV-side fuses needed to protect a 3x140kVA, 12470/208 YNyn0 distribution transformer bank. Show and explain step by step the procedure you employ to solve this question. Use the type K and type T fuse curves
A 60O lossless line is connected to a source with Vg=10
A small magnetic needle, which is free to turn slowly in a horizontal plane, is placed at the center of the coil in question (6). Show that it will set at an angle \(\phi\) to B where \(cot(\phi) = 4R/(\pi n^2 \mu_{o}\omega a)\)
A single-phase half-wave rectifier is fed with a triangular signal with period 2 . The maximum positive and negative amplitudes are ± 12 V rms. determine: a) The value of the DC output voltage. b) The percentage of curly
Design a circuit that takes the output from each of the five microphones your band uses and adds the voltage to create a single voltage signal which is fed to the amplifer. Except not all voltages should be equaly amplified.
Use MATLAB to generate a 256x256 black image (0 values) with a 1-valued central block (white square) of 64x64 size. Analytically or graphically define/derive how to determine the rotation angles and different coordinates systems.
at the frequency f=12khz, a filter is designed to attenuate the input signal by 78db, find the amplitude of the output signal if the 12khz input has an amplitude of 1V.
