Electrical Machines Fundamentals
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…
Hi, I am Jared, welcome to Fun Science Demos. We are kind of in the dark today because we are talking about electricity. And to show you electricity, we need to light up some light bulbs. And to light up some light bulbs, we need it a little bit dark. I have in front of…
Have you ever wondered how a flashlight works? Sure, it seems pretty simple…all you have to do is move a switch or press a button, and…ta da! The light comes on! But what really makes the light go on? Right you are, Squeaks! It’s electricity that makes the light go on. You probably already know…
Suppose we take our circuit of a battery and a light bulb, and we make it slightly more complicated by adding a switch. When the switch opens, the charged particles are prevented from passing through. Particles with the same charge repel one another, and they therefore spread out throughout the wire. The events shown here…
Now, I would like to explain about the wiring a little more in detail. A figure like this that shows a pictorial representation of an electrical circuit is called a “wiring diagram”. It is helpful when you are wiring devices or assembling a machine. However, when the wiring is complicated, it’s difficult to understand the…
[animation of electrons flowing from a battery to light bulb in a loop] Let’s begin by looking at how a simple circuit allows a light bulb to light. A circuit is a route through which electrical current can flow. In our example, [arrow pointing to the negative side of the battery] electrons flow from the…
This video is just the basics of electronic components, what they look like and what they actually do – and how they work in fact So let’s start with one of the most common, the one that I just picked up there the resistor So this is a one thousand Ohm resistor I can tell…
