8. How does the internal resistance of the interfaceaffect the time constant?
   Qualitatively describe how the curve would be different if there was no
   internal resistance.

Hook a second resistor into your circuit in series with the first resistor.
Should this increase or decrease the time constant?? Repeat this experiment and
analysis for this new circuit. Be sure to answer all questions.
