Electronic circuits
Let’s create some circuits. First, we will use crocodile clips, a battery holder, a battery, and LEDs to complete two circuits. We will look at circuit design with the following:
- Electricity in series
- Electricity in parallel
As we learned previously, as electricity travels through a circuit and its components, from a point of higher voltage to lower voltage, the electric potential is used up by the components it flows through until there is no more potential energy. So, how we arrange our components will influence how the electricity is consumed. Let’s look at series and parallel circuits, using an LED to demonstrate.
Series
For components to be in a series, they are connected one after another. Electricity will pass through the first component, then through the next, and so on:

The schematic shown in Figure 2.11 shows three LEDs in a series. We can...
