Visual Cue Narration
Slide 1: Welcome to the spoken tutorial on AC and DC Circuits using circuitjs simulator.
Slide 2:

Learning Objectives

In this tutorial, we will learn about the
  • current flow in the AC and DC circuits
Slide 3:

System Requirement

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

Pre-Requisites

To follow this tutorial, you should have a basic knowledge of
  • Electrical circuits

DC Circuit.png

We will make this DC circuit for demonstration

For this circuit we require

  • 1 Resistor of 10 Ohms.
  • 1 DC Source Power Supply of 5 Volts.
Let us open the circuitjs interface as shown.

In the menu bar, click on File and select New Blank Circuit.

Draw => Add Resistor Click on Draw and select Add resistor.

Click and drag to draw a resistor in the work area as shown.

By default the value of this resistor is 1K Ohm.

Change the resistor value from 1K Ohm to 10 Ohms using the edit option as shown.

Next, we have to add the DC power supply to the circuit
Click on Draw, >>go to Inputs and Sources, >> select Add Voltage Source (2-terminal).

right-click on the source and choose Swap Terminals.

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

Add the DC power supply in the work area parallel to the resistor as shown.

Look at the circuit diagram to see the polarity of the power supply.

If you need to change it, right-click on the source and choose Swap Terminals.

The DC power supply starts at 5 Volts, which is good enough.

So we don't have to change it.

Point to the components. We have all the required components in the work area.

Now let's connect the components using wires.

From the Draw menu, select Add Wire. From the Draw menu, select Add Wire.

Connect the resistor and the DC power supply as shown.

Observe the yellow dots in the circuit.

Note that for the DC power supply, the conventional current flows in a single direction.

Video of complete circuit with graph (explaining the nature of the voltage and current) Graphical representation of voltage and current helps us to understand the concept better.
Right-click on the DC power supply >> select View in New Scope option. Right-click on the DC power supply and select View in New Scope option.

Notice the voltage and current values are plotted on a graph at the bottom of the screen.

The green line represents the voltage and the yellow line represents current in the circuit.

The waveform shows that the current and voltage in the circuit flows in a straight line.

Slide:

Assignment: DC Circuit

As an assignment, do the following.
  1. In the above DC circuit, change the resistor value from 10 Ohms to any value between 2 Ohms to 8 Ohms.
  2. Notice the change in the conventional current flow in the circuit represented by the yellow dots.
  3. Check the graphical representation of the yellow line which represents the current in the circuit.

AC Circuit.png

Now, we will make this AC circuit for demonstration

For this circuit, we require

  • One Resistor of 10 Ohms
  • One AC Source Power Supply of 5 Volts
Replace the DC power supply with AC power supply Notice that, apart from the power supply, the AC circuit is similar to the DC circuit.

Hence, we will remove the DC power supply from this circuit and add an AC power supply.

Right click on the DC power supply and select delete option.

Show the path to find the AC Power Supply.

Click on Draw, and go to Inputs and Sources.

Select Add A/C Voltage Source(2-terminal) option.

Next we have to add the AC power supply in the circuit.

Click on Draw, and go to Inputs and Sources.

Select Add A/C Voltage Source(2-terminal) option.

Draw and connect the AC power supply in the circuit.

The default value of the AC power supply is 5 Volts.

Video of complete circuit with graph (explaining the nature of the voltage and current) Observe the yellow dots in the circuit.

Observe the direction of current flowing in forward and backward directions,

This represents AC.

Right-click on the AC power supply and select View in New Scope option.

Graphical representation of voltage-current helps us to understand the concept better.

For that, right-click on the AC power supply and select View in New Scope option.

Notice the voltage and current values are plotted on a graph at the bottom of your screen.

The green line represents the voltage and the yellow line represents current in the circuit.

The current in an AC circuit fluctuates forwards and backward.

Hence we see a sinusoidal wave.

Assignment 2 As an assignment, do the following.
  1. In the above AC circuit, change the resistor value from 10 Ohms to any value between 2 Ohms to 8 Ohms.
  2. Notice the change in current flow of the circuit represented by the yellow dots.
  3. Check the graphical representation of the yellow line which represents the current in the circuit.
Comparison between

AC and DC power source

Slide:

Few key points of comparison between AC and DC power source are:

AC is most suitable for household and industrial applications

DC is used in electronics, portable devices and vehicle electrical systems

AC is generated by power plants and is ideal for long distance transmission;

DC is generated by chemical reactions in batteries

Slide: AC power is more dangerous when it comes to electrical shocks;

DC is considered safe for low voltage applications

This brings us to the end of this tutorial.

Let us summarize.
