Electrons and holes are moving in a uniform, one-dimensional electric field E = +2500 V/cm. The electrons and holes have mobilities of 700 and 250 cm2/V · s,respectively. What are the electron and hole velocities If n =1017/cm3 and p =103/cm3
The required exposure energy for a positive photoresist is 140 mJ/cm2 and for a negative photoresist is 9 mJ/cm2. Assuming negligible times for loading and unloading wafers, compare the wafer throughput for positive photoresist and negative photor..
Suppose that we need a first-order RC low pass filter with a half-power frequency of 1 kHz. Determine the value of the capacitance, given that the resistance is 5 k Ω.
A 440-V three-hase Y-connected synchronous motor has a synchronous reactance of 1.5 ohms per phase. The field current has been adjusted so that the torque angle is 28 degrees when the supplied power to the motor is 90kW.
If the amplitude of the incident wave voltage at theload is 100V, determine the amplitude of the total voltage at theload, the distance from the load to the first voltage minimum and the amplitude of the voltage at this minimum.

What is the new resistance level of a copper wire if the length is changed from 200ft to 100yd, the area is changed from 40,000CM to 0.04 in.^2, and the original resistance was 800m ohms. CM stands for circular mill not cm^2.
Create a message signal and a carrier signal and apply a simplified amplitude modulation (DSB-SC-AM) to see the modulated signal in time domain.
The signal is known to contain components with frequencies up to 30 kHz. What is the minimum sampling rate that should be specified? Suppose that we want the resolution of the sampled values to be 0.1 percent (or better) of the full range of the A..
