Step 1: Understand what resistivity is. Resistivity is a measure of how strongly a material opposes the flow of electric current.
Step 2: Know that different materials have different resistivity values. Metals generally have low resistivity, while insulators have high resistivity.
Step 3: Identify common materials used in electrical applications, such as copper, aluminum, and silver.
Step 4: Compare the resistivity values of these materials. Look for a reliable source or table that lists resistivity values.
Step 5: Find that silver has the lowest resistivity value compared to other common materials.
