What is the total power density and total available current density between wavelength of 280 and 1240 nm for the AM0 and AM1.5 spectra.Assume each photon generates on electron-hole pair. You will need AM1.5 and AM1.0 spectra - which you can download from NREL's web site.
A.) We would like to use a series lumped element b to match this load. What is the length of the line where the normalized input impedance is z= 1-jb(d/\lambda). If the rfequency is 1GHz , find the value of the lumped element(C or L).
The speed of a 10HP, 230V, 1200 rpm separately excited DC motor is controlled by a 1-phase full-wave bridge converter. The rated armature current of the motor is 10 A. The armature resistance is 0.25 Ohm and the armature inductance is 10 mH.
Describe why interrupts are not appropriate for implementing synchronization primitive in multiprocessor systems.
Finding peak amplitude, frequency, and spectrum shape, b. A signal generator outputs a unipolar square wave with a period of 0.50 ms and an amplitude of 2.0 V. The output of the generator is passed through an ideal band pass filter that has a pass..
Find the impulse response fpr the filter? How many nonzero terms does the impulse response contain?
When the piston is at its bottom dead center, the gas is initially at 10 psig, 65°F, and 10.5 in 3 . After compression and when the piston is at top dead center, the gas is 180°F and occupies 1.5 in 3 . What would be the new pressure of the gas in..
Give a different equation, in terms of the input and output, to describe the system. Is the system stable?
Power factor improvement, An industrial user has a number of machine tools which are driven by three phase induction motors. during a particular shift, the power factor of the combined load can vary between 0.65(100 KVA load) and 0.81 (20 KVA) loa..
What is the maximum number of consecutive bits that are in error for a transmission through this channel if the data rate is 10Kbps? If the data rate is 11 Mbps?
A three-phase transmission line having a reactance of 120 ohms per phase is connected to a wye-connected load whose resistance is 160 ohms per phase. If the supply volatge is 70kV line-to-line, calculate a) The line-to-neutral voltage per phase.
Given the electric field E=4xux+2yuyV/m find the voltage between the points A(2,0) and B(0,2) integrating along: (a) straight line AB; (b) broken line AOB, where O(0,0).
A pulse width modulation (PWM) circuit works by varying the duty cycle of the square wave while keeping the period fixed.
