An ideal abrupt silicon pn junction has a \(N_{A} = 2 x 10^{17} cm^{-3} , N_{D} = 2 x 10^{15} cm^{-3} , \) 1) With derivation steps, calculate internal potential barrier V0 at 300K and 400K, respectively
The following test data were taken on a 110-KVA, 4400/440- volt, 60-Hz transformer: Short Circuit Test: P= 2000w, I = 200 amp, V = 18v Open Circuit Test: P=1200w, I= 2 amp, V = 4400v Calculate the voltage regulation of this transformer when it suppli..
A series circuit with R =2 ohm, L = 2 mH, and C =500 mF has a current which increases linearly from zero to 10A in the interval 0
determine the maximum rms voltage, the resonant frequency, the half-power frequencies, and the bandwidth. Use the results to determine the quality factor of the circuit.
The amount of heat Q needed to turn a mass, m, of room temperature ( T_1) water into steam at 100 Celcius. ( T_2) can be found using the specific heat, c, of water and the heat of vaporization, H_v, of water at 1 atmosphere of pressure.
A 480-V, 60 Hz, 400-hp 0.8-PF-leading eight-pole Δ-connected synchronous motor has a synchronous reactance of 1.0Ω and negligible armature resistance. Ignore its friction, windage, and core losses for the purposes of this problem. If this motor i..
Steel surfaces can be hardened by carburization. During one such treatment at 1000°C, there is a drop in carbon concentration from 5 to 4 at% carbon between 1 and 2 mm from the surface of the steel. Estimate the flux of carbon atoms into the steel
(a) Three volts is applied across a 1-cm-long semiconductor bar. The average electron drift velocity is 104 cm/s. Find the electron mobility. (b) If the electron mobility in part (a) were 800 cm2/V-s, what is the average electron drift velocity
Calculate the peak current and the apparent power supplied to the load.
The average orbital radius of Neptune is 2.8 billion miles. Given that distance, how long on average does it take light from the sun to reach the planet Neptune in hours (Speed of light in English system = 186,282.4 miles/second)
a dsp system is given with the following specifications: design requirements: sampling rate 20,000 Hz Maximum allowable gain variation from 0 to 4,000 Hz = 2dB 40dB rejection at the frequency of 16000 Hz
