Question: 1 / 400

What does resistance indicate about a material?

The ability to transfer heat

The level of electrical conductivity

Resistance is a measure of how strongly a material opposes the flow of electric current. It indicates the level of electrical conductivity of the material. When a substance has high resistance, it means that it does not allow electric current to pass through easily, which signifies low conductivity. Conversely, materials with low resistance facilitate the easy flow of electricity, indicating high conductivity.

The concept of resistance is fundamental in understanding how electrical circuits function; it directly affects how much current can flow for a given voltage according to Ohm's Law. Materials like metals are typically good conductors because they have low resistance, while insulators like rubber have high resistance. Thus, knowing about resistance allows one to assess the material's ability to conduct electricity effectively.
