A simple transformer is illustrated in . input load resistor laminated iron core primary coil secondary coil State why the iron core is laminated, what is meant by an ideal transformer. 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 V. Calculate the peak voltage across the load resistor connected to the secondary coil. peak voltage = V
