爱迪生的实验室为制造铂丝灯泡付出了大量的努力，但这些投入都白费了，因为铂的电阻相对较低。

Edison's lab put a lot of effort into making a bulb with a platinum filament, but that work went nowhere, because platinum has a relatively low resistance.

这个小灯泡的电阻比那个大灯泡的大。

This small lamp has a higher resistance than that large one.

随着电流的增加，金属丝灯泡的电阻是增加的，而碳丝灯泡的电阻是减小的。

The resistance of the metal-filament lamp increases, and that of the carbon-filament lamp decreases with increase of current.
