Questions on transformer?

Question

Please give me the answer of these questions ( as much as u can) and i will give u your ten points.

1) Use ideas of electromagnetic induction to explain how the input voltage is transformed into an output voltage. Use the 3 questions below to help u with your answer.

a)What happens in the primary coil?
b)What happens in the core?
c)what happens in the secondary coil?

2)Explain how in the transformer :
a) a continuously varying magnetic flux is produced in the primary coil.
b)the varying magnetic flux is passed from the primary to the secondary coil.
c)an e.m.f is generated across the secondary coil.

This question is not on transformer but if u can answer it it would be great.

Why should we not handle a radioactive source with bare hands.

Answer 1

1.a) receives the alternating current.
b) the magnetic properties are altered by the electromagnetic field. .
c) by the alterations in the core induces other alternating current in this coil.
2.a) because the alternating current induces the varying magnetic field.
b) that magnetic flux is passed by the core to the secondary coil.
c) yes an alternating one.

Because radioactivity destroy organic tissues.

Answer 2

About the only thing that I see that is not covered is saturation. This is a situation when u can no longer handle an increase in the magnetic flux.
Another is if u are loading the transformer with 80% power supplies. Most power supplies conduct power in the top 30 deg. of each half cycle. This will cause a severe problem of neutral 2nd harmonic problems.and if your ground is connected to the neutral in multiple points u will have this neutral current flowing in your ground system.

Answer 3

dude, do your own homework
we are here to help but not do it for you
i can tell you this
the more the wires are coiled up the more itll output
as for the emf
its magnetized it will push a metal
like in certain pinballs
