Day 20: Sinusoids

 Lab: Phasors - Passive RL Circuit Response

Prelab:

We first had to show that the amplitude gain and phase difference were as the lab packet had implied.

Then we found the cut off frequency Wc for the values of L = 1mH and R = 47 Ohms.

Procedure:

The circuit was pretty straightforward, so the fabrication stage of this lab was a breeze.

We then input the 3 frequencies required for analysis. Using the analog discovery, we displayed the v(in) - yellow, the v(L) - blue, and the i(in) - red by using the equation:

To measure the Gain we used:

and for the Phase difference we used:

Wc/10 = 4.7k

Wc = 47k

Wc*10 = 470k

Here are some tabulated results for the gain, and percent differences.
