Q: What is the effect of increasing the length of a conductor on its resistivity?
Solution:
Resistivity is an intrinsic property of the material and does not change with length.
Steps: 4
Show Steps
Step 1: Understand what resistivity is. Resistivity is a property of a material that tells us how much it resists the flow of electric current.
Step 2: Know that resistivity is determined by the type of material, not its shape or size.
Step 3: Realize that when we increase the length of a conductor (like a wire), we are changing its resistance, not its resistivity.
Step 4: Remember that resistivity remains constant for a given material, regardless of how long or short the conductor is.
