Design a noninverting amplifier with gain of 20. Maxium opamp output current of 0.5 mA should occur for maximum outputvoltage of 8 V.
Use the Schroedinger wave equation to derive an expression for the confined energies of an electron trapped between two barriers separated by a distance, a. Hint: Take the potential to be constant and equal to zero between 0 and a
Consider a virtual memory system that can address a total of 232 bytes. You have unlimited hard drive space, but are limited to only 8 MB of semiconductor (physical) memory. Assume that virtual and physical pages are each 4 KB in size.
A starship of mass (2.0?106 kg) uses its tractor beam to pull a shuttlecraft (2.0?104 kg) aboard from a distance of 10 km away. The tractor beam exerts a constant force of 4.0104 N on the shuttlecraft. Both spacecraft are initially at rest.
The nameplate on a 50-MVA, 60-Hz single-phase transformer indicates that it has a voltage rating of 8.0-kV: 78-kV. An open-circuit test is conducted from the low-voltage side, and the corresponding instrument readings are 8.0kV, 62.1A, and 206kW.
Determine the output voltage for an op-amp comparator circuit with a non-inverting input reference voltage of + 2 VDC and an inverting input signal of - 1 VDC. The op amp reaches output saturation voltages of + or -13 V at the limits.
Water is the working fluid in a vapor power cycle with reheat, superheat and reheat. Superheated steam enters the first turbine stage at 8 MPa, 480 C and expands to 0.7 MPa
(a) Find the inverse Laplace transform of df(t)/dt by differentiating f(t) and then using the Laplace transformtables.(b) Find the inverse Laplace transform of df(t)/dt by using the theorem for differentiation.
The equivalent circuit parameters are R1=0.48 ohms, X1=0.80 ohms, R2'=0.42 ohms, X2'=0.80 ohms, Xm=30 ohms The motor is operating with slip of 0.04. Find the input current and power factor.
Design an experiment that allows frequencies between 300-3300 Hz to pass with a 14 dB gain. At f = 10 KHz and f = 100 Hz, the gain should be -16 dB. Use a cascaded design consisting of first and second order Butterworth sections.
A spherically-symmetric charge distribution in free space (with a
In addition, the distance between the components of the exciton is always such that there are intervening semiconductor atoms. Thus e in the Bohr formulation must also be replaced by Ks e0, where Ksis the semiconductor dielectric constant.
a) If the excitation voltage E0 is equal to the terminla voltage ( 4kV ), what is the maximum real power which the motor can deliver without losing synchronism b) What is the rotor pole shift in electrical degrees, corresponding to the nominal loa..
