| A big capacitor |
In the first part of this course, we learned about current, voltage, and the
simplest kinds of circuits, and developed an analogy between fluid systems
and electrical systems.
This second part explores electricity further;
this section is a review of the basic concepts of electricity
and introduces two new circuit elements: the light emitting diode and the
capacitor.
