Why is the efficiency of a transformer not determined by direct loading?

Could you please clarify the question? Also, where are these transformer questions coming from? Are you reading a textbook or online resource about transformers?

Probably because large transformers are too efficient.

If a transformer is 99% efficient then an errow of 1.1% in reading primary or secondary volts or amps could give you an efficiency greater than 100%.

Our professor gave these questions as an assignment.

Thanks for your opinion.

Then these questions belong in the Homework Help forums, either in Intro Physics or Engineering. Please do not post schoolwork questions here in the EE forum.

And you need to post the Relevant Equations and your Attempt at a Solution when posting schoolwork questions here on the PF.

I'll move this thread now, leaving an expiring redirect behind in EE.
