Visual Cue Narration
Slide 1: Welcome to the spoken tutorial on Voltage Divider circuits
Slide 2:

Learning Objective

In this tutorial, we will learn how,
  • The input voltage divides among the components in the circuit
  • To manage the output voltage of the circuit by changing the values of resistors
Slide3:

System Requirement

To record this tutorial, I am using:
  • Ubuntu Linux 20.04 OS
  • CircuitJS Application
Slide 4:

Prerequisite

To follow this tutorial, you should have a basic knowledge of
  • Electrical circuits and
  • Series and Parallel Resistance
We will create this Voltage divider circuit for demonstration.
Show the diagram

Voltage divider.png

For Voltage Divider circuit we require
  • 2 Resistors of 1 Kilo Ohms
  • 1 DC power supply of 12 Volts and
  • Analog Output
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.

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.

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.

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.

We have all the required components in the work area.

Now let's connect the components using wires.

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.

Point to yellow dots Observe the yellow dots, indicating the current flow direction in the circuit.

Observe the voltage reading at the analog output.

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.

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.

As we know, in a series resistance circuit, the voltage is distributed among each resistor.
Simulation window Now lets see the voltage divider in action.
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.

This brings us to the end of the tutorial.

Let us summarize.

Slide

Summary

In this tutorial, we learnt how
  • The input voltage divides among the components in the circuit
  • To manage the output voltage of the circuit by changing the values of resistors
Assignment: As an assignment do the following:
  • Find out the value of resistor R1, for the following condition of the circuit:

Vin = 12 Volts, Vout = 2 Volts and R2 = 2.5 Kilo Ohms
