Constant percentage & constant ohmic

If you want homework doing for you, don't just recite the question as presented on the paper.

Tony, we were all young once.

Just maybe this guy is having difficulties understanding the question that he had submitted, if we know the answer, lets help, if not don't make him look like a fool.

We all have to start some where, lets not discourage future people from learning from what we know.

I don't know the answer to his question.

I challenge you to submit the correct answer

best regards

Joe
