Guess it depends on the High School, but I had never heard of ohm's law until I went to tech school for electronics. I would be surprised to find many high school grads that knew what it was.
When I was in school we learned that in junior high science.
My wife is 17 years younger than I. We are both astounded at how much was omitted from high school between the years I went and when she went. (We went to the same school, by the way.) As a college professor today, she is dismayed at the lack of skills and knowledge so many come to her with.
