Current electricity is what charges your devices and lets you watch tv. This lesson will teach you about what current electricity is and the different components that are used in electric circuits and the function of each of the different types of components in the circuit.
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.
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.
