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

|- style="border:1pt solid #000000;padding:0.176cm;"
|| <div style="color:#ff0000;"></div>

'''DC Circuit.png'''

|| We will make this DC circuit for demonstration

For this circuit we require
* <div style="margin-left:1.27cm;margin-right:0cm;">1 Resistor of 10 Ohms.</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">1 DC Source Power Supply of 5 Volts.</div>

|- style="border:1pt solid #000000;padding:0.176cm;"
| style="color:#ff0000;" |
|| Let us open the '''circuitjs''' interface as shown.

In the menu bar, click on '''File''' and select '''New Blank Circuit.'''
|- style="border:1pt solid #000000;padding:0.176cm;"
|| 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.
|- style="border:1pt solid #000000;padding:0.176cm;"
||
|| Next, we have to add the DC power supply to the circuit
|- style="border:1pt solid #000000;padding:0.176cm;"
|| 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.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Point to the components.
|| 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;"
|| 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.

|- style="border:1pt solid #000000;padding:0.176cm;"
|| 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.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Slide:

Assignment: DC Circuit
|| As an assignment, do the following.
# <div style="margin-left:1.27cm;margin-right:0cm;">In the above DC circuit, change the resistor value from 10 Ohms to any value between 2 Ohms to 8 Ohms.</div>
# <div style="margin-left:1.27cm;margin-right:0cm;">Notice the change in the conventional current flow in the circuit represented by the yellow dots.</div>
# <div style="margin-left:1.27cm;margin-right:0cm;">Check the graphical representation of the yellow line which represents the current in the circuit.</div>

|- style="border:1pt solid #000000;padding:0.176cm;"
|| <div style="color:#ff0000;"></div>

'''AC Circuit.png'''
|| Now, we will make this AC circuit for demonstration

For this circuit, we require
* <div style="margin-left:1.27cm;margin-right:0cm;">One Resistor of 10 Ohms</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">One AC Source Power Supply of 5 Volts</div>

|- style="border:1pt solid #000000;padding:0.176cm;"
|| 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.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| 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.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| 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.

|- style="border:1pt solid #000000;padding:0.176cm;"
||

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.
|- style="border:1pt solid #000000;padding:0.176cm;"
|| Assignment 2
|| As an assignment, do the following.
# <div style="margin-left:1.27cm;margin-right:0cm;">In the above AC circuit, change the resistor value from 10 Ohms to any value between 2 Ohms to 8 Ohms.</div>
# <div style="margin-left:1.27cm;margin-right:0cm;">Notice the change in current flow of the circuit represented by the yellow dots.</div>
# <div style="margin-left:1.27cm;margin-right:0cm;">Check the graphical representation of the yellow line which represents the current in the circuit.</div>

|| 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

|- style="border:1pt solid #000000;padding:0.176cm;"
|| Slide:
||AC power is more dangerous when it comes to electrical shocks;
DC is considered safe for low voltage applications
