Energy & Electricity in Science : How Does Wave Energy Work?

Hi, I’m Steve Jones and I’m going to tell you a little about how wave energy works. The first thing to understand this, that the energy comes from the movement of the wave as the wave goes past the point through a various different types of energy that can be harness in this way, but […]

Energy & Electricity in Science : How Does an Electric Motor Work?

Hi, I’m Steve Jones and I’m going to explain how an electric motor works. Now I’ve drawn this diagram, it looks rather complicated but it isn’t really that complicated. There are two main elements. The first is this pair of magnets, one with a north here, the other with a south here. These are usually […]

Energy & Electricity in Science : How Does Electricity Light Up a Bulb?

Hi, I’m Steve Jones and I’m going to tell you how electricity lights up a bulb. Well, the bulb doesn’t really light up unless there is a coating on it, it is the filament inside which lights up and the filament is made usually of something called tungsten which is a very hard material and […]

Energy & Electricity in Science : How Does an Electric Circuit Work?

Hi I’m Steve Jones and I’m going to explain how an electric circuit works. Well first of all we have to remember that there are certain things which conduct electricity which we call conductors and there are others which don’t conduct which are called insulators. Now conductors and insulators you must know the difference between […]

Energy & Electricity in Science : How Does an Electric Water Heater Work?

Hi. My name is Steve Jones, and I’m going to explain how a water heater works. Now, in this system, I have a cylinder. Usually in your house, you’ll find a cylinder. And the cylinder contains a large amount of water, maybe up to 200 liters, depending where you live. This water has to be […]

Energy & Electricity in Science : How Does a Solenoid Work?

Hi, I’m Steve Jones and I’m going to tell you how a solenoid works. Well first of all, what is a solenoid? It’s very simple, it is a coil of wire. This is usually copper wire and as you can see here, it’s coiled around like this, around some kind of former, this may be […]
