This is the block 4, C-kits in series.
00:00:00
In this exercise, you have to calculate several questions here.
00:00:05
First, I recommend you to draw the C-kit.
00:00:11
Three resistors in series and the cell.
00:00:16
First questions.
00:00:18
The first question is to calculate the equivalent resistance.
00:00:20
The equivalent resistance in the C-kitting series is the addition of all the resistors that you have in the C-kit.
00:00:24
So, you have this result.
00:00:32
The total current always is the voltage of the cell divided by the equivalent resistance.
00:00:34
Make the calculation with the calculator.
00:00:39
In the following question, they are asking you the current in every of the resistors.
00:00:43
here what you have to know is a property of the circuits in series the intensity or current is
00:00:48
always the same so it's equal to the total intensity because there is only one path for
00:00:57
the electron for the electrons to go through the circuit but in question d they are asking you to
00:01:03
calculate voltage in every of the resistors then apply the ohm's law in each of the resistors
00:01:10
because you know the intensity and you know the resistance and then calculate in each resistor
00:01:17
that's why i call them voltage sub one means for the voltage in the resistor number one
00:01:24
intensity by resistance in all of them use the calculator again so you always have the same
00:01:32
intensity and this is the resistance of this of each of them check that the addition of the three
00:01:38
voltages is the voltage of the cell. You can use a calculator to check this.
00:01:46
In the last question, they are asking you to calculate the power, the power generated by the
00:01:54
cell and the power dissipated by each of the resistors. The power is the voltage by the
00:01:58
intensity. So the power generated is the voltage of the cell by the total intensity of the CKIT.
00:02:04
then the power generated is this amount the power dissipated is dissipated in each of the
00:02:12
resistors that they are the load devices the devices that are creating our work
00:02:18
in each of them you can calculate the voltage by the intensity because you know it from the
00:02:22
previous questions so you calculate the power in the first resistance the power in the second and
00:02:29
the power in the third multiplying the voltages that you obtain and the intensity remember that
00:02:35
was the same the unit of the power is the butt and it's really little the these figures are
00:02:41
really little because the voltage of the cell was only three volts is really small and the
00:02:48
intensity was only 0.1 amperes one thing that you have to check is that the addition of the three
00:02:55
power dissipated in each of the resistors the addition of these three
00:03:03
it's exactly the same as the power that you have in the cell.
00:03:09
That's why we can say that the power generated is equal to the power dissipated in the circuit.
