What is the effect of temperature on the resistance of a conductor?
Resistance increases with temperature
Resistance decreases with temperature
Resistance remains constant
Resistance is independent of temperature
For most conductors, resistance increases with temperature due to increased lattice vibrations that impede electron flow.

Q: What is the effect of temperature on the resistance of a conductor?
Solution: For most conductors, resistance increases with temperature due to increased lattice vibrations that impede electron flow.
Steps: 6
Step 1: Understand what a conductor is. A conductor is a material that allows electricity to flow through it easily, like copper or aluminum.
Step 2: Know what resistance means. Resistance is a measure of how much a material opposes the flow of electricity.
Step 3: Learn about temperature. Temperature is how hot or cold something is, and it can affect materials in different ways.
Step 4: Realize that when the temperature of a conductor increases, the atoms in the conductor vibrate more. This is because heat gives energy to the atoms.
Step 5: Understand that these increased vibrations make it harder for electrons (which carry electricity) to move through the conductor.
Step 6: Conclude that as the temperature goes up, the resistance of the conductor also goes up because the vibrating atoms block the flow of electrons more.
