Question

the potentiometer can be linear or circular in construction and has ________ electrical connecting points. a. two b. three c. four d. five

Explanation:

A potentiometer is a three - terminal resistor with a sliding contact that forms an adjustable voltage divider. If only two terminals are used (one end and the wiper), it acts as a variable resistor or rheostat. But in terms of electrical connecting points for its basic potentiometer function (voltage division), it has three points: two fixed ends and one wiper (sliding contact).

Answer:

B. Three
