This is a guided problem to help you with basic Time Constant concepts.  If you click here you can get a calculator for some time constant calculations.  Use that calculator for the questions below, as needed.

• Run the calculator and calculate the time constant(s) for the resultant graph.  Then, enter your result.  Use any algorithm you want to calculate the time constant from the data.
• Be sure that you can calculate the time constants reliably, and that you can usually get a grade in the 90s.
• Be sure that you can get the time constant for rising and falling cases.
• If you get "intractable" curves, let the plot run its course, then clear the data and start again.
