1 00:00:02,029 --> 00:00:09,289 we are going to describe some electric components the more important that we 2 00:00:09,289 --> 00:00:21,550 are going to use obviously and some of them such as resistors just only 3 00:00:21,550 --> 00:00:31,030 control the values of the current electrical current but they can also use 4 00:00:31,030 --> 00:00:40,270 as inputs in an electronic circuit if there are variable resistors or 5 00:00:40,270 --> 00:00:52,030 potentiometers because they can transform the position so a physical 6 00:00:52,030 --> 00:01:00,270 physical action into a current something that happens in the current 7 00:01:00,270 --> 00:01:22,269 Buzzers are also outputs, they emit sounds, lamps are also outputs, they can bright, and fuses are just protection elements, 8 00:01:22,269 --> 00:01:31,269 And switches are to control the circuit and the way it works. 9 00:01:31,269 --> 00:01:43,290 The resistor. The resistor limits the flow of electrical current through the circuit by using the Ohm's law. 10 00:01:43,290 --> 00:01:55,290 But the value of the resistors can be different and we can know by using the color code. 11 00:01:55,290 --> 00:02:05,290 A resistor such as this usually has at least four rings, four bands. 12 00:02:05,290 --> 00:02:22,469 three has different color and the fourth one yes just only be a gold or or silver so we bulb are 13 00:02:22,469 --> 00:02:33,810 very useful because they are really important and in a bulb you have the you have a distant 14 00:02:33,810 --> 00:02:50,550 filament which by Joule's effect heats a lot and it emits light when the 15 00:02:50,550 --> 00:03:01,210 heat is enough. This is its symbol. Just only to protect something, generally a 16 00:03:01,210 --> 00:03:13,030 component. By Joule's effect the filament always heats, so if the heat is 17 00:03:13,030 --> 00:03:21,069 enough the filament can melt and then the current flow, the flow is 18 00:03:21,069 --> 00:03:32,229 stopped. It's the same as a switch open. For control it can be different 19 00:03:32,229 --> 00:03:47,289 types and it just only have to position open and close one a that can allow let 20 00:03:47,289 --> 00:03:58,750 the the current flow flows can be a one switch or just a push and the other the 21 00:03:58,750 --> 00:04:07,090 other types other types is when has two or more or more ways that it it is 22 00:04:07,090 --> 00:04:19,240 usually used to two different different controls I hope it can be useful
