Day 19

Impedance Lab

Today we are looking at three different circuits and comparing the impedance of each of these circuits.

Here we are given our three circuits. One has 2 resistors, another has a resistor in series with an inductor, and the last has a resistor in series with a capacitor.

Here we are measuring the output current from the 47 ohm resistor and the output voltage of the 100 ohm resistor.

Here we are calculating the theoretical values of each of the circuits so we can test them to the experimental values.

Here are some sexy pics of the circuit with the resistor and the capacitor in series.

Here is our updated data sheet with values of each of the circuits at different frequencies.

And now here is a sexy pic of a circuit with an inductor in series with a resistor.

This is our updated data sheet from the above experiement where we are testing the inductor in series with the resistor at different frequencies.

Graphs

Here is the collection of graphs and plots for each of the circuits at different frequencies. We can see that each one behaves differently and how different circuits are out of phase. We can see how some circuits will lead and others will lag.

Overall impedance ties a lot of ideas together and we can see how different components will affect the overall behavior of the circuit.
