Combination of Resistance (Parallel Connection)

 

Project Aim:

To understand the effect of resistance in parallel connection on circuit behavior, that we will observe from LED intensity.

Components Used:

1.     Power Supply

2.     Resistors of 2.2K & 4.7K

3.     LED

4.     Connecting Wires

Connection Procedure:

Step 1: Connect the one end of 2.2K ohm resistor (R4, Pin 7) to one end of 4.7k ohm resistor (R5, Pin 9). Again, connect another end of 2.2K ohm resistor (R4, Pin 8) to another end of 4.7k ohm resistor (R5, Pin 10). This makes the connection of Resistors in Parallel.

Step 2: Now, Connect the positive terminal of the power supply (Pin 62) to one end of the parallel resistors, connect to any one pin (R4, Pin 7) or (R5, Pin 9).

Step 3: From another end of parallel resistors, any one pin (R4, Pin 8) or (R5, Pin 10) connect to Anode of the LED (Pin 45).

Step 4: Connect the Cathode of the LED (pin 46) to the negative terminal of the power supply (Pin 59).

Step 5: Ensure that the power supply is connected to a power source, and the circuit is complete.

Step 6: Observe the LED for illumination, indicating that the circuit is functioning properly.

 

Explanation:

In a parallel connection, resistances are linked between two points, each with its own current direction. This setup divides the current into different paths, which then join back together. As a result, the overall resistance decreases, leading to brighter LED lights. Additionally, if one part of the circuit fails, the others typically continue to function.
