We learnt about components in circuits and we learnt that resistors can be useful in our everyday lives. We now look at three effects that electrical current has such as the heating effect, the magnetic effect and the chemical effects.

Series circuits
In a circuit, we can set up the components in such a way that the current only has one pathway to follow or multiple pathways. In this lesson we are going to look at the different setups and investigate the benefits of having one pathway.
-
Parallel circuits
Parallel circuits have more than one pathway for a circuit; we use lightbulbs to illustrate how this circuit conducts electricity.

Resistance of different materials and...
Some materials have high resistance and others have low resistance. In this lesson we will learn about how to test the resistance in different materials.
