In this video we introduce the concept of impedance. Impedance is how we will relate voltage and current in the frequency domain for AC circuits (think of it like Ohm’s Law for the frequency domain). Impedance allows us to solve AC circuits using the strategies we have explained before in DC circuits, and gives us the tools we need to completely understand any AC circuit.
If you have any questions, please leave them in the comments here or on YouTube, and I will be happy to answer them.
