Circuit Schematic

For this lab we  examined the response of a RC circuit. We measured the difference in circuit response in a switching on and off of a DC input. For this circuit we used a 22 uF capacitor, a 1KΩ resistor (R1) and a 2.2KΩ resistor (R2).

Graph of Results

Above is a graph of the response from the circuit. A trigger is needed in order to grab the results after removing the power source.

Summary:

Today, we analyzed first order circuits which are circuits that involve a circuit element such as an inductor (RL) or capacitor (RC). These circuits are characterized by a differential equation. For the experiment it was found that the way in which we reduce the applied voltage effects the circuit's natural response. By turning off the power supply, it does not disconnect the power supply from the circuit but simply acts as a short which as a result left R1 to be included in the circuit and reduced the amount the time needed for the capacitor to discharge.
