• Where are we going to find time constants?
• Actually, they are found in numerous systems including:
• Thermal systems
• Rotational systems (motors starting up)
• etc.
• What is a time constant?
• A way of describing how quickly a system responds to changing inputs, and a fundamental parameter in many systems.
• Where do they come from? Link to material on thermal time constants
• How do you calculate them once you have lab data?  Link to material on ways to calculate a time constant

2. Example(s) of time constants

• An example - finding time responses in a time constant system.

3. Getting a time constant from numerical data.  (See link below)

4. Something to watch for in thermistor circuit time constant calculations.
