When we want to tell someone about an electrical device we have made, we
need to specify what is connected to what, and how. This is most easily
done using a pictoral language, in which the electrical components are
reduced to simple sketches. The elements of this language are given in the
table below.
It is assumed that the wires are covered with an insulator (colored plastic,
in the case of the wires in your kit). Then wires that cross each other
don't make a new conducting path.
| component name | representation |
|---|---|
| battery (A) | |
| wire (B) | |
| intersecting wires | |
| nonintersecting wires (C) | |
| motor (D) | |
| light bulb (E) | |
