design a capacitor as a main energy storage device for a all electric car. The capacitor has to have the following specifications: Needs to provide 100 horsepower for 10 hours Max operation voltage of 480V The min and max for the dielectric and metals are: 10 nm < tdielectric < 10 µm, 10 ?m < tmetal < 10 cm Need to find the following for the design: Weight and volume of capacitor Total energy the capacitor can store The material used The operation voltage used Really.
Then find the total energy stored in the battery before it is connected to the bulb. Determine the total amount of charge that has pessed through the wires that connect the battery and the bulb.
A single phase transformer has the following rating: 120 kVA, 2000 V/100 V, 60 Hz with 1000 primary turns. Determine: (a) the secondary turns (b) the rated primary and secondary currents (c) the maximum flux
Compare MOSFET devices to BJT devices. Specifically, which devices are minority carrier devices and which devices are majority carrier devices. What impact does this have Also, compare power consumption, speed, integration, and preva- lence.
What RF bandwidth must the radio link provide if the modulation is binary phase shift keying (BPSK)?
The stepped cylindrical tank is initially filled with liquid water at STP to a height H1. Subsequently, a plug at the bottom of the tank is removed to allow water to flow from the small hole of diameter d. The velocity v of the flowing water
1.)Using the SR0 instruction write the vbc1 assembly code that displays the One-Hot counter from left to right. 2.)Write the VBC1 assembly code that resembles the following behavior
A 460-V, three-phase,60-Hz system supplies power to a 10-kVA, delta-connected resistor load; a 50-kVA, 0.86 power factor induction motor, and a wye-connected synchronous motor that is operating at 0.62 power factor leading
1.Explain aluminum migration in device contacts, and propose possible solutions for the aluminum spikes caused by the migration. 2.What are the two methods for the first step of impurity doping Why a second drive-in step is needed
A liquid level system converts a 4-10 m level into a 4-20mA current. Design a three mode controller (PID im assuming) that outputs 0-5 volts with 50% PB, 0.03 min integration time, and 0.05 min derivative time. Fastest expected change time is 0.8 ..
An engineer decides to take 600 samples at sampling frequency 9000Hz. A Fast Fourier Transform (fft) program was applied to obtain the frequency spectrum of the signal. What is the frequency resolution,df, for the analysis
A plane circular disk of radius 0.25m rotates at a speed of 200 rad/s about an axis through the center of the disk perpendicular to the plane of the disk. There is a uniform magnetic flux B = 1 Tesla parallel to the axis of rotation.
