I was trying to keep it simple, which is why I went for the resistive load rather than a transformer - in which case current and voltage are proportional. In my experience of teaching electronics, people always find voltage is easier to visualise (and put on a 'scope) than current.
But yes, when you put the transformer in circuit, then it's the current that matters - and my explanation falls down because there's only ~20V DC across the transformer primary
