transformers.

Question 1

what are the 4 steps of a transformer working?

Answer 1

close switch allows current to flow.
iron core becomes magnetised- little magnets point same way- lines of magnetic flux.
change in magnetic field in coil- field lines cut.
produces an induced potential difference and if there is a closed circuit a current flows.

Question 2

what type of current is passed through the coil?

Answer 2

alternating current.

Question 3

what does a transformer produce, where?

Answer 3

alternating magnetic field in the iron core.

Question 4

what do the flux lines of the alternating magnetic field do?

Answer 4

pass through and cut the secondary coil.

Question 5

what does the transformer process induce?

Answer 5

alternating potential difference in the secondary coil.
