PRE-LAB QUESTIONS
Please complete the following questions before coming to the lab, and bring your answers with you to the lab:
1. What is the resistance of the voltmeter?
2. Why should you avoid touching the conductive sheets?
3. How can you determine the direction of the electric field?
4. What is an equipotential line? How can a set of these lines be used to determine the electric field lines?
Set yourself the following objectives for this lab:
- Learn how to measure the electric potential and electric field surrounding charged parallel plates
- Study the difference between electric potential and field inside and outside parallel plates.
