PRELAB QUESTIONS: (to be turned in upon arriving at lab)

Reflection: Circuits. These first couple of "reflection" questions will not be graded, we just want to know your opinion regarding the most recent lab, in which you constructed some simple circuits using real wires, power supply, and batteries.

1. I thought this lab was __________ USEFUL for learning about circuits.

very
pretty
somewhat
barely
not at all

(not answered)

2. I thought this lab was __________ ENJOYABLE for a physics lab.

very
pretty
somewhat
barely
not at all

(not answered)

3. Very briefly, compare that lab with the one the week earlier still, which used the Phet (computer) circuit construction simulation. In what ways did working with the simulation help you learn better, and/or how did working with real bulbs help you more? Did you have a preference for one lab over the other? Try to come up with something brief, concrete, and constructive - this will help us improve our labs for future 2020 students!




Prelab6 on AC Signals

1. Read the lab thoroughly.

2. Familiarize yourself with an oscilloscope and an electrocardiogram (Chapter 17.10 and 17.11)

3. What is an oscilloscope used to measure?

4.

The picture is a typical display you may see on an oscilloscope. Assume that the volts/div setting is 50 V/div and the time/div setting is 5 ms/div. What are the period, frequency and amplitude of this signal (Do not forget the units)?

Period:

Frequency:

Amplitude:


Thanks for your time and efforts!


Optional! - below is a space for any additional relevant comments, thoughts, or suggestions you have. If you want to elaborate on any "multiple choice" questions, do so here. It can also be about anything you'd like to tell or ask relating in some way to this class! If you expect a reply, however, it's much better to email Prof. DeWolfe or Prof. Pollock.




We thank you for taking the time to fill out this pretest.
