The flow or movement of electric charge through a material, such as when electrons move through a conductor.
电阻 (diànrǔ): The property that opposes the flow of electric current in a material.
导体 (dǎotǐ): Materials that allow electric charges to pass through them easily due to their high conductivity.
绝缘体 (juéyuántǐ): Materials that do not allow electric charges to pass through them easily due to their low conductivity.
