Q
Q: Which material has the highest resistivity?
Solution:
Rubber has a much higher resistivity compared to metals like copper, aluminum, and iron.
Steps: 5
Show Steps
Step 1: Understand what resistivity means. Resistivity is a measure of how much a material resists the flow of electric current.
Step 2: Know that different materials have different resistivity values. Metals usually have low resistivity, while insulators have high resistivity.
Step 3: Identify common materials. Examples of metals include copper, aluminum, and iron, which have low resistivity.
Step 4: Compare these metals to insulators. Rubber is an example of an insulator, which has a much higher resistivity than metals.
Step 5: Conclude that among common materials, rubber has the highest resistivity compared to metals like copper, aluminum, and iron.
