When we first make an electrical circuit, we might just make it with a battery and a bulb.
We can then start adding more components - but adding more components can change how the circuit works.
For example, if you add more light bulbs to a series circuit, each bulb might not shine as brightly as they are sharing the electricity.
However, if you add more light bulbs to a parallel circuit, each bulb will continue to shine just as brightly because they each have their own path for electricity flow.
Adding more batteries to a circuit can make it more powerful, and adding more switches gives you more control over the circuit.
In this activity, we will look at what happens when we add different components.
Let's get started.
