Lab Day 14

Passive RC Circuit Natural Response Lab

In this lab assignment, we examined the natural response of a simple RC circuit. We used both manual switching operation and a square wave voltage source to create our circuit's natural response. We then saw the method used to create the response affects the circuit being measured.

This is the pre-lab, we estimated the initial capacitor voltage and the time constant for the circuits. Also the measured resistance and capacitor values.

This is an image of the oscilloscope window, showing the capacitor voltage for the first circuit, in which V+ is used as the voltage source.

This is the measured data and the calculated data from the pre-lab. The percent error is shown as 2.9% this is because the resistance values were a little off.

This is an image of the oscilloscope window, showing the capacitor voltage for the second circuit, in which the waveform generator is used as the voltage source.

This is the measured data and the calculated data from the pre-lab. The percent error is shown as 0.8% this is because the resistance values were a little off.

This is a picture of our circuit.
