What is the effect of increasing the diameter of the potentiometer wire on its resistance?
Correct Answer: Resistance decreases.
- Step 1: Understand what a potentiometer wire is. It is a type of resistor used to measure voltage or current.
- Step 2: Know that resistance is a measure of how much a material opposes the flow of electric current.
- Step 3: Learn about the diameter of the wire. A larger diameter means a thicker wire.
- Step 4: Recognize that the cross-sectional area of the wire increases when the diameter increases.
- Step 5: Remember the relationship between resistance and cross-sectional area: resistance decreases as the area increases.
- Step 6: Conclude that increasing the diameter of the potentiometer wire decreases its resistance.
