Trace the Characteristic
Sweep the voltage and plot the I-V characteristic for a metal conductor, a filament lamp and a diode, and see why only the first is a straight line through the origin.

Which component has a straight-line I-V graph through the origin?
componentmetal conductor
voltage V3.0 V
current I0.60 A
Ohmic conductor: I ∝ V. Filament: resistance rises with heat. Diode: conducts one way only.
