(Optional) Describe the operation of variable resistors.

Description should include

• explaining the process and function of variable resistors
• identifying examples of variable resistors, such as potentiometer and rheostat
• using an ohm meter to measure the value of variable resistors.

Process/Skill Questions:

• How would a variable resistor be used in a circuit?
• What is the advantage of using a variable resistor inside a circuit?
• How does one determine whether a variable resistor is working as intended?
