**What This Document Is**
This is a laboratory worksheet designed for a third-year physics course focused on electrical measurements. Specifically, it’s Lab Four for PHYS 301 at Western Kentucky University. The worksheet guides students through a series of practical exercises centered around temperature sensing using thermistors and related data acquisition techniques. It’s structured as a hands-on activity to reinforce theoretical concepts learned in the course. The lab explores the characteristics of thermistors, their response to temperature changes, and comparison with other temperature sensors.
**Why This Document Matters**
This worksheet is essential for students enrolled in Lab Electrical Measurements (PHYS 301). It’s intended to be used *during* a lab session, providing a structured framework for recording observations, performing calculations, and analyzing experimental results. Students preparing for the lab will find it helpful to review beforehand to understand the expected procedures and data to be collected. Successfully completing this lab and associated worksheet will demonstrate a practical understanding of sensor behavior, data acquisition systems, and error analysis – skills crucial for any aspiring physicist or engineer.
**Common Limitations or Challenges**
This worksheet does *not* contain background theory on thermistors, ADC’s, or related concepts. It assumes students have already received instruction on these topics. It also doesn’t provide pre-filled data or solutions; it’s designed to be completed through active experimentation and analysis. The worksheet focuses on a specific lab setup and may not be directly applicable to other experimental configurations. It also doesn’t offer detailed troubleshooting guidance for equipment malfunctions.
