voldge across the resistor Procedure: 1. Assemble the circuit as shown in the figure. 2. Connect the voltage graphing instrument across the resistor. 3. Set the battery voltage as 10V. This voltage is recommended due to mesh in the graphing device. 4. Run the experiment. You may obtain a graph like shown in the figure below. 5. Measure half time ts2 from the graph and calculate the time constant using eq. (3) 6. Repeat this for minimum two values of capacitance and two values of resistance.

Problems: 1. What is the maximum amount of charge that was stored in your capacitor? How much energy is stored in the capacitor when fully charged? Consider any one of the cases 2. Based on your experimental results of the half-life time (tu), how long will it take to charge your capacitor to 75% its maximum value? Consider any one of the cases. 3. What is the role of resistor in RC circuit? How does the current in resistor vary when the capacitor is charging?
4. Draw the voltage across the resistor and across the capacitor as a function of time when the capacitor is charging, 5. A 1.2uF capacitor with an initial stored energy of 0.50J is discharged through a 1.0MQ resistor. (a) What is the initial charge on the capacitor? (b) What is the current through the resistor when the discharge starts?
