An electrical conductor is a substance that allows an electrical current to pass through it and an insulator is a non-conducting material that does not carry any charge.We take a closer look at electrical cells and batteries as well as the different types of conductors that we find. We also take a closer look at resistors in a circuit.

Series circuits
A series circuit provides only one path for electric current to move through the circuit. We study what happens when more cells or resistors are added into a series circuit.
-
Parallel circuits
A parallel circuit provides more than one path for the electric current to move through the circuit. We investigate what happens when we add cells in parallel in a circuit.
-
Safety with electricity
Households use parallel circuits to ensure energy flow for multiple rooms. We discuss the different safety measures that are in place in our homes and appliances and we also look at the dangers associated with electricity.
