Ah. I just looked up the Shockley equation, and indeed there is an ideality factor between 1 and 2 multiplying kB. The lab manual gave us the equation without that factor.. Bastards eh? A few other people in my class said they also got a kB value that's about twice the actual value.
In any...
So the current through a diode as a function of applied voltage is:
I = I0 [ exp( V q / KB T) - 1 ]
where V is the voltage (independent variable), q is the charge of the electron (constant), T is temperature (constant over each trial), I0 is some parameter that's measured to be really tiny (I...
I'm trying to do this demonstration for a high school class:
Using different shapes of "boats" I'm going to demonstrate how each boat shape affects the flow of water across it - does the water glide smoothly around the boat or become turbulent? My professor briefly mentioned that "rheostatic...
Homework Statement
Given a particle is confined in a one dimensional harmonic oscillator potential, find the matrix representation of the momentum operator in the basis of the eigenvectors of the Hamiltonian.
Homework Equations
Potential: V(x) = 0.5 m w^2 x^2 where m is the mass of...
I realized a mistake in my earlier analysis; when the electron enters the nucleus, r is not 0 but rather on the order or 10^-14 - this means when the electron enters the nucleus, the electric potential energy does not diverge to negtive inifity like I first thought - so I integrated P from...
I understand Rutherford proposed that electrons orbit around a central nucleus. However, since accelerating charges produce electromagnetic radiation, the orbiting electron should lose energy via E&M and spiral into the nucleus.
But my question is: How do I calculate the time it takes for the...
