Q: What is the effect of temperature on the resistance of the potentiometer wire?
Solution:
The resistance of most conductive materials increases with temperature due to increased atomic vibrations that impede electron flow.
Steps: 6
Show Steps
Step 1: Understand what a potentiometer wire is. It is a type of wire used to measure voltage or resistance.
Step 2: Know that resistance is how much a material opposes the flow of electric current.
Step 3: Learn that temperature can affect how well electricity flows through a wire.
Step 4: Realize that when the temperature of the wire increases, the atoms in the wire vibrate more.
Step 5: Understand that these increased vibrations make it harder for electrons (which carry electric current) to move through the wire.
Step 6: Conclude that as the temperature goes up, the resistance of the potentiometer wire also goes up.
