Position Sensing — Quiz
Test your understanding of position sensing with 5 practice questions.
Practice Questions
Question 1
Which type of encoder uses a unique pattern of opaque and transparent segments on a disk to provide an absolute position reading, even after power interruption?
Question 2
A rotary potentiometer has a total resistance of $5 \text{ k}\Omega$ and a total angular travel of $300^{\circ}$. If the wiper is at an angular position of $120^{\circ}$ from the start, what is the resistance between the wiper and the start terminal?
Question 3
In vision-based position sensing, which advanced technique is primarily used to identify and track specific objects or features across a sequence of images, even with variations in lighting, scale, or orientation?
Question 4
Which of the following describes a key advantage of using resolvers over optical encoders in applications where high levels of vibration and shock are present?
Question 5
A linear potentiometer has a total resistance of $10 \text{ k}\Omega$ and is supplied with a voltage of $12 \text{ V}$. If the output voltage measured at the wiper is $4.8 \text{ V}$, what is the percentage of the wiper's travel from the start terminal?
