Draw an i-v curve (current vs. voltage) for a metallic resistor. 2) add an i-v curve with a different color for a resistor with higher resistance than the previous one. 3) draw an i-v curve for a light bulb. (note that the filament in the light bulb is tungsten, a metal with a high melting point, gets hotter with more applied voltage. for metals, the resistance increases with temperature.)
