|| <div style="color:#000000;">In the menu bar, click on the '''Circuits '''menu'''.'''</div>

<div style="color:#000000;">You can see a list of ready to use electronic circuits.</div>

<div style="color:#000000;">Basic circuits such as '''Diodes, OP-AMPs, 555 Timer Chip''' and many other circuits are available.</div>
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
| style="color:#000000;" | Basic Circuits - Potentiometer
|| <div style="color:#000000;">Let us see the working of a few circuits available here.</div>

<div style="color:#000000;">Go to the '''Basics''' in the list and select the '''Potentiometer''' circuit.</div>

<div style="color:#000000;">This circuit is built using a 1 Kilo Ohm potentiometer and two 5-volt power supplies.</div>

<div style="color:#000000;">On the right side of your screen, you will see a slider named '''Resistance'''.</div>

<div style="color:#000000;">This resistance slider is used to change the potentiometer value.</div>
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
||
|| <div style="color:#000000;">Notice the flow of electrons on both sides of the circuit.</div>

<div style="color:#000000;">The resistance value is 500 Ohms on each side of the circuit.</div>

<div style="color:#000000;">Use the slider to lower the potentiometer value.</div>

<div style="color:#000000;">Notice the flow of electrons in the left side of the circuit.</div>

<div style="color:#000000;">Electrons in the left side move much faster than the electrons in the right side of the circuit.</div>

<div style="color:#000000;">This is because the resistance for the left side of the circuit is less than that of the right side.</div>

<div style="color:#000000;">Now, change the potentiometer value by increasing the resistance slider.</div>

<div style="color:#000000;">For this condition, the electrons on the right side of the circuit are moving faster.</div>

<div style="color:#000000;">This is because the resistance for the right side of the circuit is less than that of the left side.</div>

<div style="color:#000000;">The flow of current in the circuit depends on the resistance of the circuit.</div>
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
| style="color:#000000;" |
|| <div style="color:#000000;">Now, let us open another circuit and explore it.</div>

<div style="color:#000000;">Click on the '''Circuits''' menu, go to '''Diodes''' and select the '''Half wave rectifier '''from the list.</div>
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
| style="color:#000000;" | Half Wave Rectifier
|| <div style="color:#000000;"></div>

<div style="color:#000000;">This circuit is built using a diode, an AC power supply and a resistor.</div>

<div style="color:#000000;">The half wave rectifier converts only one cycle of an AC supply into a pulsating DC output.</div>

<div style="color:#000000;">At the bottom of your screen, two graphs are displayed.</div>

<div style="color:#000000;">Input voltage is shown on the left graph and output voltage is shown on the right graph.</div>

<div style="color:#000000;">The diode allows either the positive or negative cycle of the input signal to pass through.</div>

<div style="color:#000000;">In this circuit, the diode is connected in forward bias.</div>

<div style="color:#000000;">It allows only the positive half cycle of the input signal to pass through.</div>

<div style="color:#000000;"></div>
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
| style="color:#000000;" |
|| <div style="color:#000000;">Change the orientation of the diode for the reverse bias mode and notice the changes.</div>

<div style="color:#000000;">For this right click on the diode and select '''Swap terminals '''option'''.'''</div>

<div style="color:#000000;">Note the graph.</div>

<div style="color:#000000;">We can see the diode is passing the negative half cycle of the AC signal to pass through.</div>

|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
| style="color:#000000;" | '''Half Wave Rectifier with capacitor'''
|| <div style="color:#000000;">We will now add a capacitor to the circuit and attempt to get a pure DC output.</div>

<div style="color:#000000;">First, use the '''swap terminals''' option to change the orientation of the diode to forward bias.</div>

<div style="color:#000000;">Now, click on '''Draw''' menu, go to '''Passive components''' and select '''Add Capacitor (Polarized)'''</div>

<div style="color:#000000;">Drag and draw the capacitor in the working area.</div>

<div style="color:#000000;">Make the changes in the circuit to connect the capacitor parallel to the resistor as shown.</div>

|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
| style="color:#000000;" |
|| <div style="color:#000000;">Use the '''edit''' option to change the capacitor value to 1000 microfarads</div>

<div style="color:#000000;">Notice the changes in the output graph.</div>

<div style="color:#000000;">Changing the capacitor value can result in a pure DC output.</div>

<div style="color:#000000;">The half-wave rectifier converts AC to pulsating DC by permitting current flow in one direction.</div>

|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
| style="color:#000000;" |
|| <div style="color:#000000;">Let us study another circuit available on the '''CircuitJS''' platform.</div>

<div style="color:#000000;">Click on the '''Circuits''' menu, go to '''Transistors''' and select '''Multivibrators.'''</div>

<div style="color:#000000;">Then choose the '''Astable Multivibrator '''circuit.</div>

<div style="color:#000000;">An astable multivibrator circuit will be shown on your screen.</div>
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
| style="color:#000000;" | '''Astable Multivibrator'''
|| <div style="color:#000000;"></div>

<div style="color:#000000;">To understand how an astable multivibrator works, we will add two LEDs to the circuit.</div>

<div style="color:#000000;">Click on '''Draw''', go to '''Outputs''' '''and''' '''Labels''', and select '''Add LED '''option'''.'''</div>

<div style="color:#000000;">Drag and draw the LED in the working area.</div>

<div style="color:#000000;">Now, remove the wire connected to the collector terminal of the Q1 transistor.</div>

<div style="color:#000000;">Replace the wire with the LED.</div>

<div style="color:#000000;">Similarly, remove the wire connected to the collector terminal of the Q2 transistor. </div>

<div style="color:#000000;">Now, right click on the LED component and click on the '''Duplicate''' option.</div>

<div style="color:#000000;">A new LED will be generated in the working area.</div>

<div style="color:#000000;">Connect this LED in the circuit as shown.</div>
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
| style="color:#000000;" | '''Astable Multivibrator'''
|| <div style="color:#000000;">Capacitor C1 controls the LED connected to the Q1 transistor.</div>

<div style="color:#000000;">Capacitor C2 controls the LED connected to the Q2 transistor.</div>
<div style="color:#000000;">Notice the LEDs are turning ON and OFF at alternate times.</div>

<div style="color:#000000;">The LED is turned OFF when the capacitor is charging.</div>

<div style="color:#000000;">And the LED is turned ON when the capacitor is discharging.</div>

<div style="color:#000000;">The value of both the capacitors C1 and C2 is 18 microfarads.</div>
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
| style="color:#000000;" |
|| <div style="color:#000000;"></div>

<div style="color:#000000;">Let usincrease the capacitor value to see the changes in the circuit.</div>

<div style="color:#000000;">Use the '''edit''' option for both the capacitors and change their values to 100 microfarads.</div>

<div style="color:#000000;">Notice the turn ON and turn OFF timing of both the LEDs have increased.</div>

<div style="color:#000000;">This is because of the change in values of the capacitors.</div>

<div style="color:#000000;">Higher value capacitor takes more time to charge and discharge.</div>

<div style="color:#000000;">Thus, while the capacitor is charging, the LED is turned OFF.</div>

<div style="color:#000000;">And when the capacitor is discharging, the LED is turned ON.</div>

<div style="color:#000000;">The astable multivibrator is used for signal generation and timing applications.</div>

<div style="color:#000000;">It offers continuous oscillation without external triggering.</div>
|- style="border:1pt solid #000000;padding:0.176cm;"
