Given a potential block of 10ev with a length of 10nm, derive and determine the transmission reflection coefficients for a particle traveling with an energy (a) 2ev and (b) 20ev. If the block is given infinite potential and the length is expanded to 1m,(c) what would be the transmission and reflection coefficients?
The stator resistance Rs is 0.25 Ω, and the stator as well as rotor leakage inductances are negligible. All losses except in the stator and rotor resistances can also be neglected. The reflected rotor resistance, Rr' is 0.3 Ω. The magnetizing curr..
Create a non-inverting op amp circuit to obtain Vout = 12 V if R2 (RF) = 1100k-ohm and Vin =1V . Open up the attributes window of the op amp (click on the op amp symbol) and verify that VPOS = +15V and VNEG = -15V. Do not change any other attribut..
Find an expression for the potential at any point (x, y), assuming zero volts on the z-axis. When calculating the potential, you may start with the potential of a single infinite line charge, assume a reference point on the z-axis, and use superpo..

A design problem: As we said earlier, the backbone of any design is ‘thorough analysis' of the problem or circuit at hand. We have analyzed above the voltage divider circuit. Utilizing the above analysis, determine R1 and R2 of a voltage divider c..
Consider a 1-cm thick slab of crown glass, with index of refraction n =1.52. (a) If a beam of visible light at 500nm is normally incident from one side of the slab, what percentage of the incident power transmits to the other side
A new phone company wants to provide very cheap voice-only cell phone capability to 200,000 simultaneous users in San Francisco. They transmit only 8kbs per duplex channel using FDMA (frequency division multiple access) and BPSK (1 bit/Hz).
a. Neglecting resistance, determine the synchronous, transient and sub-transient reactances. b.If the machine is delivering 1.0 p.u. current at 0.8 power factor lagging at the rated terminal voltage when the short circuit is applied.
Drift velocity the actual (physical) velocity of electrons along the wire. Transmission velocity the rate at which information can be transmitted electronically using conducing wires. How is it possible that the transmission velocity is so much faste..
