| Circuit Built |
The circuit built for this lab included a 1Ω resistor and a 1uH inductor.
 |
| Results |
For our pre-lab we calculated the phase shift and the amplitude gain of Vout and Vin. Vin is the voltage that was supplied to the circuit (1.5V) and Vout was the voltage from the inductor.

| Oscilloscope |
We measured Vin and Vout using the oscilloscope from the Analog Discovery and used the math channel to plot Iin(t) ((Vin-Vout)/R). It is shown that Vin and Vout have different amplitudes and are out of phase.
Summary:
The purpose for the lab today was to analyze the steady-state response of electrical circuits from sinusoidal inputs. We were able to find the amplitude gain by comparing the phasors representing Vin and Vout. We also learned how to analyze AC circuits using different methods of analysis. These methods include, nodal analysis, mesh analysis, superposition, thevenin and norton analysis. We can use theses methods the same way we would for a DC circuit except this time we will be using jimaginary numbers.
