Circuit diagrams
You don’t necessarily need the diagrams in this manual in or-
der to successfully set up the experiments. But they help you to
better understand everything. A circuit diagram shows the wir-
ing of components in a simplified way using switching icons
for each component. Once you get familiar with the diagram,
you will easily understand how everything works together.
The battery has six 1.5V battery cells. The longer dash indi-
cates the positive pole. The fuse is drawn as a box with a
wire. Right now, the switch shows an open connection. The
resistance is shown as a box. And the LED has an arrow that
points towards the direction of the current flow. Two small
arrows represent the light produced. In this diagram, you can
clearly see that all the components form a closed path, a cir-
cuit. There is but one point where the path is broken: at the
currently open switch.
