Unit 6 - Dirrect-Current Circuits

Unit 6 is the second biggest unit of E&M, combining what you learned about individual capacitors and resistors and connecting them through wires and batteries. Make sure you take your time with this unit, as it is almost guaranteed to be one of the three FRQ topics, and will come up again for Unit 10 (where you'll learn about the other two types of circuits you're expected to know). Skills like Kirchoff's rules and the derivations for voltage, current, and charge functions are tough to master, but they are crucial for scoring well on the exam. This is also the last unit before magnetism is introduced, so enjoy it!

Completing all lessons in this unit takes approximately 11.5 hours.
