Day 20 (Impedence Lab)

We started the day by analyzing an AC RC circuit using phasor analysis and find the current in the circuit.

We then did the same analysis for an AC RC circuit and find the voltage across the capacitor as a function of time.

We then started the Impedence Lab. Here are the pictures of the pre-lab.

Here is a picture of the input voltage versus the current in the circuit for the resistors.Under it are the results of changing frequency and seeing how the current gain and phase angle changes.

Here is a picture of the input voltage versus the current in the circuit for the inductor. Under it are the results of changing frequency and seeing how the current gain and phase angle changes.

Next we looked at adding impedences of different elements in AC circuits.

We then analyzed a voltage divider in AC using phasors.

Finally we analyzed the phase shift that an element would have, like a capacitor.
