Thanks for the reply, i updated my question a little. What i am still confused about, is how there could be different levels of polarization, which is dependent on how the dielectric is introduced into the system. (case 1 and 2) - based on energy conservation

Does this mean that in the first case there will be less polarization since when the slab in centered it will have some kinetic energy as well being polarized

U = (1/2)CV^2 = (1/2)Q^2 /C Increasing C while keeping Q constant (isolated capacitor) will decrease the energy contained in the capacitor by and amount X Where does this X energy come from? Case 1 (slab polarizes immediately when it crosses the electric field of the plates) The capacitor...

Hi My textbook mentions "We know that in an electrostatic situation (with all charges at rest) the electric field at every point in the interior of a conducting material is zero. If E were not zero, the excess charges would move" Can this actually be true since charges can still be...

Hi You guys probably have heard about the monkey and hunter problem. Basically in the monkey an hunter problem you can see the dart hits all the time if you observe the experiment in an accelerated frame of reference ie your falling with the monkey. You see the bullet travel in a straight...

finally found it out for those who want to know >> y = sym('y(t)') y = y(t) >> f = diff(y,2) + diff(y,1) + y f = diff(y(t),$(t,2))+diff(y(t),t)+y(t) >> pretty(f) / 2 \ |d | /d \...

Hi is it possible to represent unknown functions eg x(t) in MATLAB equations ? eg have f = x'' diff(f) = x' or have a derivative represented via differential eg dx/dt

sorry this is wrong, the alpha beta filter equation is not a recurrence relation..

The alpha beta filter equation is given by this Xni = AXn + BXn-1 Xn-1 is subscript i want to figure the solution to this recurrence relation, but is it a recurrence relation? i am wondering weather alpha beta filters grow faster than exponential smoothing filters.- i said it is a 1st order...

I am just wondering, how do we add an ideal BJT npn transistor to an LT Spice circuit? From the component button i have added an 'npn1' will the default values be ideal? And what if you want to change the beta for the transistor how do you do this. I found a file called standard bjt, it...

Homework Statement Discrete mathematics is it possible to have a generating function where there is an n term outside the sum? such as 2^n SUM ( bn(0.5)^n * z^n) eg the 1st turn would be 2^n bo z^0 when you evaluate the series it evaluates to the series which i am trying to...

[FONT="Times New Roman"][SIZE="3"]When the NPN is in the forward active mode The base emitter junction is forward biased and the base collector junction is reverse biased. But isn't it possible for the base collector junction to break down? Or do we assume it never breaks down? Also does...

edit... I think it may be localised build up of majority charge carriers electrons in the n material ect

[FONT="Times New Roman"] [SIZE="3"]This is a picture of my interpretation so far. The contact charges occur in the boundary of the depletion region. The region where the contact charges occurs is not between the boundary of to different materials. I am wondering what causes these...
