Purpose: To observe exponential decay function of a capacitor discharging through a large resistor and to measure indirectly the total charge on a fully charged capacitor from the sear under the discharge curve. Also to find the capacitance of the capacitor and to derive the exponential decay function and calculate the time constant of the circuit. Procedure: 1. Connect circuit in figure 3 and the LabPro Interface. 2. Close the switch to position A to charge capacitor. 3. Open switch and click collect 4. Immediately switch the switch to position B as soon as data is being taken. 5. Run for 800 seconds. 6. Repeat steps 1-4 for 400 seconds with the unknown capacitor. Data: See attached Results: As data began recording for the known capacitor (1030 μ F) a voltage of 4.945 V was measured with a current running through of 0.04945 mA. After 200 seconds a voltage of 0.6520 V was recorded with a current of 0.00652 mA.At the midway point of 400 seconds a voltage of 0.095239 V was recorded with a current of 0.00095 mA.
