The Case(i) transformer Emf across a straight conductor of length L due to non-uniform magnetic field (B.cosωt) is
Here also changing magnetic field (B.cosωt) pierces the straight conductor of length L, it's not a coil so there is only L in formula not area dA.
the above formula is not my own...
the induced EMF would be zero.. But that must be not correct, as from the working principle of transformers there must be an emf given by the Case(i) from the file or may be else, that what really confusing me, please clarify it..
I googled a lot and every time what i can found is the emf generated only for a conductor coil/loop in a changing magnetic field (B.cosωt),
and that general vector equation is
or
Here N is the number of turns in coil, A is the area of the coil and hence B.A is the flux Φ linked with that...
I have searched a lot, Please check the file from here ...
In this file Case(i) is the problem i mentioned in my post,
Please explain/elaborate Case(i) emf for me.
In my above attempt I have used the transformer emf formula, in that formula I just used a straight conductor instead of a coil..
I saw that result in a website a long time ago and that site is not available right now. that's why i am not sure about the result.
Homework Statement
What is the EMF generated in a straight conductor of length L placed in a time varying magnetic field B as
shown in the below figure..
Homework EquationsThe Attempt at a Solution
Time varying magnetic field is B.cosωt,
EMF = (d/dx)(B.L.cosωt) = -B.L.ω.cosωt
I don't know...
Hello everyone,
Where can i get dielectric loss values of very thin SiO2 layers (nm) at high frequency range (GHz).?
i.e SiO2 oxide layer dielectric loss of MOS (metal-oxide-semiconductor).
I searched a lot on net but i didn't find any useful result, any reference is greatly appreciated.
Homework Statement
I am trying to calculate the charge density in the first subband (n=1) of the quantum well of length L as shown in the below figure.
here is the electron wave function for the first sub-band and its value (from relevant equation 1) is given as
Ψ12(x) = 2/L*sin2(πx/L)
from...

Thanks for your reply, Please check this Slide's 9th page,
there we can see step like 2-d density of states (DOS) merging to form 3-D DOS under bias.
Hello everybody !
Recently i heard that, application of an electric field onto a quantum well tilts the quantum well
and changes its 2-D density of states to 3-D bulk density. Is this true..?
Can anybody give some more information or reference on this..?
Thanks for any Help.
Hello to all !
In MOSFET at strong inversion electrons confined to triangular quantum well, electrons occupy only 1 or 2 lowest subbands.
and the Van Dort model gives the quantum mechanical intrinsic carrier density in inversion channel via increased energy band-gap(ΔE).
NQM = NCL× Exp(-ΔE/2kt)...
