1. Use the time you measured for 50% discharge to calculate the resistance of the light bulb with uncertainty. You may neglect the uncertainty in the voltage measurement.

2. Using the resistance you calculated from the 50% discharge, calculate the time you expect the capacitor to take while discharging to 10%. Is this expected value consistent with your measured value?

Time for 50% discharge:

1.41 s

1.41 s

1.50 s

1.38 s

1.48 s

Time for 10% discharge:

3.66 s

3.76 s

4.10 s

3.93 s

4.21 s
