Pressure in the electrostatic field. A parallel plate capacitor with very large plates, separated a distance d apart is given. The space between the plates is filled with a dielectric with relative permittivity of 2. A potential V is connected across the plates. Assume the distance between the plates is small. Calculate the pressure the plates exert on the material between the plates.
Light Traveling an optical fiber (n=1.44) reaches the end of the fiber and exists into air. Answer the following questions: a. if the angle of incidence on the end of the fiber is 25 degress, what is the angle of refraction outside the fiber
Measurements taken on various resistors are shown below. For each, calculate the power dissipated in the resistor and the power rating necessary for safe operation using standard components with power ratings of 1/8 W, 1/4 W, 1/2 W, 1 W, or 2 W
A shunt regulator utilizing a zener diode with an incremental resistance of 5ohm is fed through an 82ohm resistor. If the raw supply changes by 1.0V, what is the corresponding change in the regulated output voltage
Using eye diagram drawings of PAM NRZ waveforms used to transmit bits in the baseband show and explain how awgn can effect bit error rates and how timing jitter can effect bit error rates.
A silicon p-n-p transistor has impurity concentrations of 5*10^18, 2*10^17, and 10^16 cm^-3, diffusion constants of minority carriers 52, 40, and 115 cm^2/s and minority lifetimes of 10^-8, 10^-7, and 10^-6 in the emitter
A silicon diode with an area of 100mm´100mm is doped with ND=2e17cm-3 and NA=1e20cm-3. It has an IS=1fA, nonidealityfactor n=1 and tT=1ns. Consider room temperature of 300 Degree Kelvin.
What is the maximum power the three generators can supply in this condition without the ratings of one of them being exceeded? At what frequency does this limit occur? How much power does each generator supply at that point?
Two nickel-cadmium batteries provide electrical power to operate a satellite transceiver. If both batteries are operating in parallel, they have an individual failure rate of 0.1 per year.
GaAs LED emitting surface size is 180 um by 180 um. The doping levels are NA = 9 E+15 cm-3 and ND = 5 E+17 cm-3. The n-layer is 70 um thick, and the p-layer is 8 um thick.
The couple M acts in a vertical plane and is applied to a beam oriented as shown.
