Well, this is block number 9. 00:00:00
You have to say which leads will work. 00:00:03
So, as usual, take from the positive to the negative. 00:00:06
From the positive, this one is not going to pass here. 00:00:09
The intensity is not going to pass, but this one, yes. 00:00:15
So, number 2 is going to work. 00:00:17
And this one, again, from the positive to the negative, this one is going to work. 00:00:20
And this one is also going to work. 00:00:26
In C, I'm going from the positive to the negative 00:00:28
It is supposed that this one is going to work 00:00:33
We continue, this one is not going to work 00:00:35
And number 3 allows electricity to go through 00:00:39
So 1, 3, and again you continue 00:00:43
And 4 is going to work 00:00:46
So here, 1, 3, and 4 00:00:48
In this one, number 1, from the positive to the negative 00:00:50
Number 1, it's supposed to be working 00:00:54
number two no number three it's supposed but see here the difference number four 00:00:56
makes this C kit to be open so none of them none are going to work in this 00:01:02
exercise we have to say if the lamps will be working or not if they it will 00:01:13
depend on the position of the diodes these are not LEDs these are diodes so 00:01:17
from the positive to the negative in this first one there is a path okay so 00:01:23
this one will be working in the second branch this diode makes that the 00:01:27
electricity that cannot go through it so this one is not going to work and the 00:01:34
third one is going to be lighting also in this exercise we are going to see we 00:01:38
can see here that this LED it's avoiding the electricity to go through the rest 00:01:43
of the circuit so none of the lamps will be working and finally in this exercise 00:01:49
We have two potentiometers, so we can vary the resistance in these two resistors. 00:01:53
In this first one, when I move the toggle of the resistor, the lamp will change the luminosity. 00:01:59
And in this one, the speed of the motor will change, having into account its potentiometer. 00:02:05
In this exercise, we have a lamp and a LED. 00:02:11
a LED the lamp is connected to an LDR so depending into the with the lighting the 00:02:16
light that is in the room this lamp will give more luminosity or less the bigger 00:02:23
is the light the smaller is the resistance so this will be lighting more 00:02:30
and here we have a thermistor that is a negative one so the bigger is the 00:02:35
temperature, the lower is the resistance, the bigger is the temperature, the 00:02:41
light here will be brighter. 00:02:47
