Periods 1-2, 8-9:
Watch and take notes on the two videos for so-called RL circuits. These are circuits that have an inductor, which is basically a solenoid, with a resistor. The symbol L stands for inductance, and it has a unit called a Henry (H). Yes, another name!
One thing that stands out as you watch these is the math analysis - it should look like RC circuits.
Check out the video on RL circuits in series.
Then, check out the video on RL circuits where things are in parallel.
When done with the videos, try to work your way through the problem set for tomorrow. On Friday, we will get into the combination of inductors with capacitors, and some interesting effects will take place!
