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