Description should include
- explaining the process and function of variable resistors
- identifying examples of variable resistors, such as potentiometer, rheostat, and digital resistor
- using ohm meter to measure the value of variable resistors
- identifying the unit of measurement for variable resistors (https://www.rapidtables.com/electric/electrical_symbols.html).
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?
