Day 17

RLC Circuit Response Lab

In this lab we were testing a RLC circuit, but this time it's not in series. So with this lab we will have a different experience then in the previous lab. Here we used a capacitor, inductor, and 2 resistors. Once again we are testing the step response and comparing the measured values to theoretical values that we derived from equations in class. These values include the damping ratio and natural frequency of the circuit.

Pre-Lab

For the pre-lab we are given the design of the RLC circuit and we are to calculate what the natural frequency and the damping ratio should be. All these values are easily obtained by the equations that we derived in class where we can compare alpha to omega.

This is the graph of our circuit in Analog Discovery where we see under damped cases every time there is an abrupt change.

Overall, we can see the relationship the circuits have in each other depending on the arrangement of the circuit and how this will affect the damping and natural frequency of the circuit.
