(a(i))[2]
State why the iron core is made into thin layers.
(a(ii))[1]
State what is meant by an ideal transformer.
(b)[2]
An ideal transformer has $300$ turns on the primary coil and $8100$ turns on the secondary coil. The root-mean-square input voltage to the primary coil is $9.0\,\text{V}$. Calculate the peak voltage across the load resistor linked to the secondary coil.
