| 5. | How many connections does a potentiometer have? |
|||||||||||||||||||
Your Answer: Option (Not Answered) Correct Answer: Option C Explanation: A potentiometer uses three connections, as opposed to a rheostat, which only employs two. Having three connections allows the potentiometer to vary voltage. Both the potentiometer and the rheostat are classified as variable resistors.
