(a) Explain the principle of transformer action.
(b) Derive an expression for the e.m.f. induced in a transformer
winding. Show that emf per turn in primary is equal to e.m.f. per
turn in the secondary.
a. Use Faraday’s Law to derive the expression for the induced
EMF for an ordinary slide generator, being careful to explain the
steps, like on an exam.
b. Use that to estimate the EMF generated across the wingspan
of an airplane flying toward Minnesota. Use the same 55.66 μT
pointed 70 degrees downward.
The wing span is 35.78 meters and cruising speed is 907
km/h.
c. First conceptual question. There is obviously not a circuit
or a current for a...
a. State the ampere circuital law
b. Derive expression for inductance of a Toroid?
c. Derive the set of Maxwell’s equations with
solutions in the integral form from the
fundamental laws of a good conductor?
d. Derive the expression for torque developed in a
rectangular closed circuit current (I) in a
uniform field?
B. Derive an expression for the mass of a particle that makes it
through the mass spectrometer as a function of: charge, q, the path
radius in the mass separator, Rpath, the magnetic field in the
velocity selector, B1, the electric field in the velocity selector,
E, and the magnetic field in the mass separator, B2.
Question

a. Derive the expression for the capacitance of a
parallel plate having two dielectric
field.
b. Write a short note on the magnetization of the
following magnetic material?
i. Diamagnetic
ii. Paramagnetic
iii. Ferromagnetic
c. Derive the
expression for torque developed in a rectangular closed circuit
current (I) in a
uniform field?
Explain the principle of “differential gene expression” and how
different genes are expressed in different cell types. Describe in
detail the two main mechanisms of the transcriptional regulation of
gene expression. If you were going to “design” a transcription
factor with an unlimited number of protein domains, how would you
design this transcription factor so that it could take care of all
of the transciptional regulation/expression of the muscle gene
myoD.
