A solar power density for a given area has a standard deviation of 3h, and a maximum power of 200W at noon. Compute the solar energy in 1 day.
Compute the equilibrium carrier concentrations and the position of the Fermi level with respect to the conduction band edge for a uniformly doped Si region with N_D=1*10^16 cm^-3 and N_A = 1*10^17 cm^-3 at room temperature.
a.) find the Fourier coefficients of the exponential form for each signal b.) Find the Fourier coefficients of the combined trigonometric form for each signal c.) Plot both the single sided and double sided amplitude and phase spectra
The terminal on the right is the positive reference for a voltage called v y (the other terminal being the negative reference). If it takes 1 mJ of energy to push a single electron into the left terminal, determine the voltages vx and vy.
Running at 1200 rpm from a 280-V source, a series-connected dc motor draws an armature current of 25 A. The field resistance is 0.2Ω, and the armature resistance is 0.3 Ω. Assuming that the flux is proportional to the field current, determine the ..
Assume that a receiver has a first amplifier stage with a 5KW input resistance, a gain of 300, an input audio signal of 20 mV, and an operating temperature of 27oC. When the amplifier is operating with a bandwidth first of 10 MHz,
4.What is the fundamental benefit of PLC controls over manual controls 5.Describe the differences between the two methods of scanning during PLC logic solving. Which method holds the advantage over the other
Find Rin, Avo, and Ro. Also, if a load resistance of 10k ohm is connected to the output, what overall voltage gain Gv is realized. Now, if a 0.2 V peak sine wave signal is required at the output, what must the peak amplitude of Vsig be.
A capacitor is made with very large plates separated a distance d. The potential between the plates is V=1000 volts and d = 1mm. a) Calculate the pressure the plates exert on the air between the plates.
