Everything in our universe, including you, is made up of atoms. At the very centre of an atom is a group, known as the nucleus, which is made up of protons and/or neutrons. The number of protons and neutrons in each nucleus is what makes materials, or elements, different. The protons are positively charged, the…

How electricity works How does electricity work. In this article we’ll be learning the basic concept behind how electricity works according to classical theory. We’ll cover Atoms, electrons, protons, neutrons then move onto the difference between conductors and insulators, wires and cables, circuits, volts and voltage, currents and amps, resistors, resistance and ohms, induction and…

We can use a battery to power some components, but usually a single battery isn’t enough to power our devices, for that we need to combine batteries. We can connect batteries in two ways. Series or parallel. We have covered these circuit types in great detail previously, check out Series HERE and Parallel HERE. When we connect the…

We need to understand some fundamentals of how electricity works before we can understand the battery. Firstly, electricity is the flow of electrons in a circuit. Batteries can provide the pushing force that moves the electrons through the circuit. The electrons want to get back to their source, and they will immediately take any path…

A typical 1.5V alkaline battery looks something like this, but the colours will vary by manufacturer. When we look at the battery, we usually have a plastic wrapper fitted tightly to the outside, this will insulate the battery but also tell us important information such as the capacity and voltage as well as which end…

What is a Battery? A battery is a device used to store energy for when we need it. We use them to power small electrical devices such as flashlights. The energy is stored as chemical energy and this can be turned into electrical energy when we need it. We’ll see how that works a little…
