Ohm’s law, *paavam*, is just V = IR. If your voltage is 10V and resistance 2Ω, current is 5A—simple table like that. But the real trick is the graph: a true ohmic conductor gives a straight line. If the graph curves, like a filament bulb, it's non-ohmic. I see this when checking faulty stabilizers—the voltage dips, but the current doesn't follow properly, just like my WiFi signal near the jamun tree.
