Understanding RC Circuits Name: Jordon Weber Date: 3/23/10 Name: ____________________________ Lab Sect.: 02 Name: ____________________________ Lab Instructor: ______________________ Lab Activity 1: Charging and Discharging of RC Circuit Q1. Sketch (qualitatively) below the time variation of the measured voltage across the capacitor. Label the point at which you switched from charging the capacitor to discharging the capacitor. (Alternatively, you can print the graph and attach it to your lab report, if you so wish.) Q2. Without doing any explicit fits to the data, use the graph displayed in the DataStudio window to estimate the time constant of this circuit. Explain how you did this! time (seconds) V C (volts)

The total voltage the capacitor received was 2.888 V. The time constant corresponds to when approximately 63% is charged. The voltage at 63% charge is 1.819 V at 7.15 seconds after is began charging.
