Please use your time in the lab to conduct the different experiments. Calculations for this experiment should be done at home after all data has been collected. You can use the oscilloscope screenshot to USB-Flashdrive function to make sure, you have all data available later. Further information on the use of the oscilloscope for this experiment can be found here. |

Tau is the time constant of an RC circuit that takes to change from one steady state condition to another steady state condition when subjected to a step change input condition [4]. τ is the time taken for the capacitor from an initial charge voltage of zero to approximately 63.2% of the value of an applied DC voltage. The change of state from one stable condition to another generally occurs at a rate determined by the time constant of the circuit which itself will be an exponential value. The time constant of an RC circuit could be used to measure the value of the unknown capacitance, given that the resistance is known:
