(a(i))[2]
State why the iron core is laminated.
(a(ii))[1]
State what an ideal transformer means.
(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 connected to the secondary coil.
