1 00:00:00,000 --> 00:00:13,050 We are learning about electricity and inventions. In this video, we will cover the components of 2 00:00:13,050 --> 00:00:30,179 electric circuits, the types of electric circuits, and how to represent electric circuits. A circuit 3 00:00:30,179 --> 00:00:38,640 is a complete path around which electricity can flow. An electric circuit 4 00:00:38,640 --> 00:00:51,179 is a closed loop or a circle. Electric circuits contain components. Electric 5 00:00:51,179 --> 00:01:02,780 circuits have four components. A generator, cables, switch, and light bulb. 6 00:01:02,780 --> 00:01:16,239 Let's look at these parts in the image. We have our generator, the socket, then we 7 00:01:16,239 --> 00:01:31,909 have the cable. Next we have the switch. It turns the circuit on or off. Finally 8 00:01:31,909 --> 00:01:39,049 we have the light bulb. It makes light when the switch is on and the circuit is 9 00:01:39,049 --> 00:01:49,849 running correctly. So we've got our generator, the socket, our cable, switch, 10 00:01:49,849 --> 00:02:06,319 and light bulb. Electric circuits. There are three types of electric circuits. There is a simple 11 00:02:06,319 --> 00:02:19,639 circuit which has one light bulb and forms a circle. Electricity flows along one path. Then 12 00:02:19,639 --> 00:02:22,419 Then we have the series circuit. 13 00:02:22,419 --> 00:02:28,000 Two or more light bulbs are connected to one battery. 14 00:02:28,000 --> 00:02:35,229 Electricity flows along one path. 15 00:02:35,229 --> 00:02:38,509 Then we have the parallel circuit. 16 00:02:38,509 --> 00:02:47,789 It forms two or more circles or paths. 17 00:02:47,789 --> 00:02:51,669 Representing electric circuits. 18 00:02:51,669 --> 00:03:01,969 We use symbols to represent the components of an electric circuit. 19 00:03:01,969 --> 00:03:07,129 Here we have the symbol for a light bulb or lamp. 20 00:03:07,129 --> 00:03:10,569 This shows a switch that is off. 21 00:03:10,569 --> 00:03:15,389 You see the line is not connected to the circle. 22 00:03:15,389 --> 00:03:18,729 This shows a switch that is on. 23 00:03:18,729 --> 00:03:21,729 It is all connected. 24 00:03:21,729 --> 00:03:32,879 we have our symbol for a battery and this line represents a wire. We can 25 00:03:32,879 --> 00:03:40,879 easily identify the components and the type of circuit. Let's use the symbols to 26 00:03:40,879 --> 00:03:52,659 identify the components of this circuit. This symbol represents the light bulb. 27 00:03:52,659 --> 00:04:07,210 This symbol represents the switch and the switch is off. The line is not 28 00:04:07,210 --> 00:04:19,540 connected to the circle. This symbol represents the battery and the line 29 00:04:19,540 --> 00:04:31,060 represents the wire. Okay this is all for today. Until next time, goodbye!
