    Regarding transformers, is the scribbling on the attached page correct?

    Yes

    Voltage and current ratios have Linear relationship to turns ratio
    Impedence ratios are "squares" of turns ratio.

    So, can we say that the impedance "follows" the voltage?

    no the impedance is relatively fixed ....
    do you know what impedance is and how it is calculated ?
