### 🔴 2: W 1/17a, 🟡 4: T 1/16, 🔵7: T 1/16 - 1F capacitor lab (2)

Last time, we learned about how to use a breadboard to build a circuit.  Today, we'll actually build a practice circuit using the 1F capacitor.  You will have to pick your own value for a charging/discharging resistor.  Then, using the data you collect using browser-based Vernier Graphical Analysis App (accessible through ClassLink), verify the time constant with two different methods.  Evaluate which method you think would be better.

Equipment: breadboard, wiring box, resistor of your choice, 1F capacitor, DC power supply, Vernier Go Direct Voltage probe, Vernier Go Direct Current Sensor probe (check what you think the max current will be in your circuit in order to set the precision switch), computer with browser-based Vernier Graphical Analysis App (accessible through ClassLink).

Then we'll do one problem to check for understanding.

Required:  2007E1 (submit with first problem set next week)

HomeworkQUIZ Tuesday, January 23rd on derivation of charging and discharging equations.  If you have not done so yet, finish pages 1-2 of Mystery Capacitor Lab and plan out how you're going to conduct the next part of the experiment outlined on page 3.  Read sections 27-3 & 27-4 in your textbook if you have not already done so.

### ❤️ 2: Th 1/18, 💛 4: F 1/19a, 💙7: W 1/17b - mystery capacitor lab (1)

Today, we will finish the one-farad capacitor lab, and I will verbally assess your understanding of the analysis.
