relationship between V, I and R in graphical terms
<< < (5/5)

Geez, guys. I realize that this is the Beginners board, but how long can one debate over a trivial 1/x relationship?!

I think it's better as an introductory teaching aid to plot current as a function of resistance, keeping voltage constant.  Then current as a function of voltage, keeping resistance constant.  Skip the variable currents; it's better to learn Kirchoff's laws first, circuit analysis, and basic semiconductor models (since these are current devices) before tackling current as anything other than a byproduct that just needs to be kept reasonable.  Semiconductors in particular are often greatly simplified through a current-centric view.
