Which of the following materials is commonly used for potentiometer wires?

Which of the following materials is commonly used for potentiometer wires?

Step 1: Understand what a potentiometer is. A potentiometer is a device that measures electrical potential (voltage).
Step 2: Learn about potentiometer wires. These wires need to have a stable resistance to work properly.
Step 3: Identify materials used for potentiometer wires. Common materials include copper, aluminum, and constantan.
Step 4: Focus on constantan. Constantan is a specific alloy that maintains a consistent resistance even when the temperature changes.
Step 5: Conclude that constantan is the best choice for potentiometer wires because of its stable resistance.
