EVALUATION OF DATA
1. Examine the potential vs. time graph for your first run. Select the region of the graph where
the potential is changing and try a natural exponent curve fit. If this function is a good match,
accept the fit. Repeat this process for your additional runs.

As you have learned, bulbs are non-ohmic; i.e., their resistance changes as the filament warms up. You will use
power resistors for the remainder of this experiment.

2. The equation that describes the time rate of change of potential during the discharge of a
capacitor is
V ? V0 e– t RC
What relationship appears to exist between the C parameter in the curve fit for each of your
runs and the product of the resistance and the capacitance in the circuit?
3. The charge stored on a capacitor’s plates is proportional to the potential difference between
them; the proportionality constant is the capacitance of the capacitor, measured in farads, F.
Examine the basic units for the farad and the ohm to determine the units for RC in the
equation above. Why must this quantity have these units?
4. The name given to the quantity, RC, is the time constant, ?. Determine the percent difference
between your experimental and expected values of this quantity. Is it within the tolerance of
the rated values for the resistor and capacitor (±10%)?
5. Examine the current vs. time graph for your final run. Integrate the area under the curve once
charge began to flow. What quantity does this area represent? Compare the value you obtain
for the area to the value you can determine from the capacitance and potential difference.
