# Physics Lab – Electrical Circuits with Resistors and Capacitors

**1. The problem statement, all variables and given/known data**

Hello, I am having trouble with a physics lab report I’m working on. I’m going to try and be as clear as possible. Basically, I’m using different values of R and C in determining tau, the time scale in a circuit’s behavior. I used a circuit with a resistor and capacitor and hooked it to an oscilloscope, and used the OpenChoice Desktop program to get 2500 data points in the capacitor voltage curve. My question is…I’m not really sure how to start plotting I guess. I have constant values of R and varying values of C and vice versa. How do I best start plotting when I have 2500 data points for each? And should I use a ln(V) vs T plot to find out what tau is? I’m sorry if this seemed vague, I can try and clarify more, but I really need help if possible! Thank you!
