- video N4: Time Constants for RC Circuits
- video N5: Review of Unit N (part 2) If you are wondering where part 1 is, this unit is both air resistance and RC circuits so part 1 in the air resistance unit in mechanics. There is a little air-resistance physics at the beginning of this one as well. You might want to pause the video each time a question is asked and try to get the answer on your own.
