|| Slide 1:
|| Welcome to the spoken tutorial on '''Voltage Divider '''circuits
|- style="border:1pt solid #000000;padding:0.176cm;"

Learning Objective
|| In this tutorial, we will learn how,
* <div style="margin-left:1.27cm;margin-right:0cm;">The input voltage divides among the components in the circuit</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">To manage the output voltage of the circuit by changing the values of resistors</div>

System Requirement
|| To record this tutorial, I am using:
* <div style="margin-left:1.27cm;margin-right:0cm;">'''Ubuntu Linux '''20.04 OS</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">CircuitJS Application</div>
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Slide 4:

Prerequisite
|| To follow this tutorial, you should have a basic knowledge of
* <div style="margin-left:1.27cm;margin-right:0cm;">Electrical circuits and</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">Series and Parallel Resistance</div>

|- style="border:1pt solid #000000;padding:0.176cm;"
||
|| We will create this Voltage divider circuit for demonstration.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| <div style="color:#000000;">Show the diagram</div>

<div style="color:#000000;">'''Voltage divider.png'''</div>

|| For Voltage Divider circuit we require
* <div style="margin-left:1.27cm;margin-right:0cm;">2 Resistors of 1 Kilo Ohms </div>
* <div style="margin-left:1.27cm;margin-right:0cm;">1 DC power supply of 12 Volts and</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">Analog Output</div>

|- style="border:1pt solid #000000;padding:0.176cm;"
| style="color:#000000;" | Keep the circuit diagram on top right
|| Let us open the '''circuitJS''' interface.

In the menu bar, click on '''File''' and select '''New Blank Circuit.'''
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Draw => Add Resistor

Right-click => Duplicate
|| Click on the '''Draw''' option and select '''Add resistor.'''

Click and drag to draw a resistor as shown.

By default, the value of this resistor is 1 Kilo Ohm.

We need two resistors of 1 Kilo Ohms for this circuit.

Right-click on the resistor and select the '''Duplicate''' option.

Place the resistors one below another as shown.

Use the '''Add Text''' option and name these resistors as R1 and R2 respectively.

|- style="border:1pt solid #000000;padding:0.176cm;"
|| Draw => Inputs and Sources => Add Voltage Source

Right-click =>Swap Terminal

Right Click => Edit..

|| Next, we have to add the DC power supply.

Click on '''Draw''', go to''' Inputs and Sources''', and select '''Add Voltage Source (2-terminal).'''

Refer to the circuit diagram shown above to check the polarity of the DC power source.

To change the polarity, right-click on the source and select the '''Swap Terminals''' option.

The default value of this power supply is 5 volts.

For our circuit, we need the DC power supply to be 12 Volts.

To change the value of the power supply, right-click on the power supply.

Select the '''Edit '''option.

Change the value from 5 to 12 in the given box as shown.

Click on the '''OK '''button to save the changes.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Draw => Outputs and Labels => Add Voltmeter / Scope Probe
|| We also need an Analog output to measure the voltage at the output.

Click on '''Draw''', go to '''Outputs and Label,''' and select '''Analog Output.'''

Click and drag to draw the analog output as shown.

Place the analog output at the junction of resistor R1 and R2 as shown.

Right click on the analog output and select '''edit''' option.

Check the box to show the voltage and click on the OK button to save the changes.
|- style="border:1pt solid #000000;padding:0.176cm;"
||
|| We have all the required components in the work area.

Now let's connect the components using wires.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Draw => Add Wire
|| From the '''Draw''' menu, select '''Add wire.'''

Connect one end of the power supply to the R1 resistor.

Connect the other end of the power supply to the R2 resistor as shown.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Point to yellow dots
|| Observe the yellow dots, indicating the current flow direction in the circuit.

Observe the voltage reading at the analog output.
|- style="border:1pt solid #000000;padding:0.176cm;"
| style="color:#ff0000;" |
|| You will see the analog output is reading 6 Volts at the output.

Click on both the resistors R1 and R2 simultaneously to check the voltage passing through it.

Both the resistors will have a voltage drop of 6V each.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Simulation window
|| The voltage at the output of a series resistor is calculated by the voltage divider formula.

Let us see the formula:

'''Vout = Vin (R1/R1+R2)'''

Where, Vout is the output voltage

Vin in the DC source used as an input

R1, R2 are two resistors used in this circuit.
|- style="border:1pt solid #000000;padding:0.176cm;"
| style="color:#ff0000;" |
|| As we know, <span style="background-color:#f7f7f8;">in a series resistance circuit, the voltage is distributed among each resistor.</span>
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Simulation window
|| Now lets see the voltage divider in action.
|- style="border:1pt solid #000000;padding:0.176cm;"
||

<div style="color:#ff0000;"></div>
|| Let us change the value of resistor R1 to 3 Kilo Ohms using the edit option and check the output.

You will see the change in the analog output reading.

Note that, the value of R1 resistor is 3 times more than the value of R2 resistor.

Hence the power supply of 12 volts is divided in the same ratio. I.e 3:1( that is 3 is to 1)

Thus, voltage passing through R1 resistor is 9 volts and through R2 is 3 volts.
|- style="border:1pt solid #000000;padding:0.176cm;"

|| This brings us to the end of the tutorial. Let us summarize.
