Circuit elements
The basic elements of circuit design are components (resistors, capacitors, and inductors), and sources (voltage and current). We describe these elements as both ideal elements and real-world objects.
We also develop precise terminology for how to talk about the parts of circuits (nodes and branches).
Finally, we learn about assigning labels to voltages and currents.
