Project Aim:

To understand the concept of conductivity by determining whether a material is a conductor or an insulator using a simple circuit with probes, an LED, and a buzzer.

Components Used:

1.     Power Supply

2.     LED

3.     Buzzer

4.     Resistor 1K

5.     Two Probes

6.     Connecting Wires

 

Circuit Diagram:

 

Connection Procedure:

Step 1: Connect one Probe to the Positive terminal of the Power Supply (Pin 62).

Step 2: Connect another Probe to the Anode of LED (Pin 47).

Step 3: Connect the Cathode of LED (Pin 48) to one end of Resistor 1K (R3, Pin 6).

Step 4: Connect another end of Resistor 1K (R3, Pin 5) to positive terminal of Buzzer (Pin 54).

Step 5: Connect negative terminal of Buzzer (Pin 53) to negative terminal of Power Supply (Pin 59).

Step 6:  Whenever we put the Probes on conducting material, the LED will glow and Buzzer will BEEP.

 

Explanation:

In this project, we aim to investigate the conductivity of different materials. A material is considered a conductor if it allows current to pass through it. Conversely, if a material does not allow current to pass through, it is termed a non-conductor or insulator. We achieve this by constructing a circuit with two probes that are connected to the material under test. If the LED connected to the circuit lights up, it indicates that the material is a conductor. On the other hand, if the LED does not light up, it signifies that the material is a non-conductor or insulator. Additionally, a buzzer is incorporated into the circuit to provide an audible indication of the material's conductivity status. Through this project, participants can gain hands-on experience in exploring the fundamental principles of electrical conductivity.
