Unit 4 - Capacitance

After Unit 3, there is a shift for the next three units of straying away from charge distributions and thinking more instead of ideal circuit components, most of which are still crucially related to electric potential. In this unit you will learn about capacitors, an arrangement of typically two parallel plates that hold a potential difference. In the real world, capacitors are most typically used to store energy in a circuit, as you will soon learn. After this unit you will learn about currents and resistors, and finally connect both units in a broader understanding of circuit behavior in Unit 6.

Completing all lessons in this unit takes approximately 8 hours.
