Combination of Resistance (Series Connection)

 

Project Aim:

To understand the effect of resistance in series 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

 

Circuit Diagram:

 


Connection Procedure:

Step 1: Connect the positive terminal of the power supply (pin 62) to one end of the 2.2K ohm resistor (R4, pin 7).

Step 2: Connect the other end of the 2.2K ohm resistor (R4, pin 8) to one end of the 4.7K ohm resistor (R5, pin 9).

Step 3: Connect the other end of the 4.7K ohm resistor (R5, pin 10) to the positive terminal of the LED (pin 45).

Step 4: Connect the negative terminal 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 series connection, resistors are linked end to end, allowing the same current to pass through each. The total resistance in the circuit is the sum of the individual resistances. As a result, the overall resistance increases, leading to a decrease in the brightness of the LED light. However, a drawback of this setup is that if any resistor fails, the entire circuit shuts off.
