> Then I realized that a 5V supply will always be 5V in normal operation and ohms law means the current varies.
This is a great observation. I've often thought that teaching Ohms law as I=V/R would lead to less confusion. Similarly, in intro physics why is mass acceleration introduced as f=ma? Wouldn't a=f/m have a clearer meaning?
