Q
Q: Which of the following materials has the highest resistivity?
Solution: Rubber is an insulator and has a much higher resistivity compared to metals like copper, aluminum, and silver.
Steps: 5
Step 1: Understand what resistivity means. Resistivity is a measure of how much a material resists the flow of electric current.
Step 2: Identify the types of materials listed in the question. Common materials include metals (like copper, aluminum, and silver) and insulators (like rubber).
Step 3: Know that metals are good conductors of electricity, meaning they have low resistivity.
Step 4: Recognize that rubber is an insulator, which means it does not conduct electricity well and has high resistivity.
Step 5: Compare the resistivity of rubber with that of metals. Since rubber has much higher resistivity than metals, it is the material with the highest resistivity.
