Astable Multivibrator using IC 555
Procedure
- Connect the components as mentioned below: L1-L12, L14-L12, L16-L12, L4-L9, L8-L9, L10-L19, L3-L17, L11-L13, L7-L19, L6-L13, L2-L13, L5-L15, L18-L9.(For eg. click on 1 and then drag to 12 and so on.)
- Click on 'Check Connection' button to check the connections.
- If connected wrong, click on the wrong connection. Else click on 'Delete all connection' button to erase all the connections.
- Intially set R a=3.3 kΩ, R b=6.8kΩ, C=0.1µf, Vcc=5 V.
- Click on "Calculate" button.
- Now note the output voltage.
- Click on "Plot" button to plot Output Voltage, Capacitance Voltage
- Click on "Clear" button to clear the data.
- Repeat the experiment for another set of resistance value.
- Set the Resistance (Ra) value (1 kΩ - 10 kΩ).
- Set the Resistance (Rb) value (1 kΩ - 10 kΩ).
- Set the Capacitance (C) value (0.1 µf - 10 µf) .
- Set supply voltage (Vcc).
