ohm's law is just v = i*r, bro. like if your phone charger’s voltage pushes current through the cable—higher voltage, more current, if resistance is fixed. you spot a non-ohmic conductor on a graph when the current-voltage plot isn’t a straight line; it curves, like a diode's graph.
honestly, i only get this because my side-project is a dumb little circuit board for budgeting alerts, and watching the voltage-current line bend on my multimeter’s display is exactly why it keeps frying—cheap parts never follow the clean theory.
