How are you all? I hope you are well, by the grace of God. I am also well today. Today I am here to share with you, conducted by @solaymann sir and @mahadisalim sir, SLC21/WK2: Introduction to Basic Electrical Circuits & Cable Joint. Thanks, @solaymann sir and @mahadisalim sir, for organising such a beautiful competition. And in today's contest, I have shown here a series circuit board and a parallel circuit board diagram as per the contest rules and a wire connection. And I thank you again for organising such a nice contest, and I'm going to start my post.

🟩What is called an electrical circuit? Mention the importance of circuits in electrical engineering.

Circuit is the path of current movement through which the current flows or moves. It is called a circuit. Wires and circuits are never the same. A circuit must have at least five components. When there are five components inside a circuit, then that circuit is called an ideal circuit.

First of all, a circuit must have an electrical source, either from a generator or from a battery. Then a conductive wire will be needed and current will flow through that wire.

Another important component of the circuit is the electrical load. A circuit must have an electrical load or resistance. Such as lamps, fans, motors, TVs, refrigerators, etc. And to control these loads, control devices such as switches must be present.

And there must be a protective device to keep this circuit board safe. Such as fuses and circuit breakers.

🟩Mention at least two differences between series circuit and parallel circuit.

Basically, circuits are of two types: one is a series circuit, and the other is a parallel circuit.

First, I will mention what a series circuit is.

A series circuit is two or more loads connected in series to an electrical source in such a way that there is only one path for current to flow. And that circuit is called series circuit.

Now I will mention what a parallel circuit is.

A parallel circuit is two or so-called loads in which all the terminals of one end are connected to one point and the terminals of the other end are connected to the voltage source in such a way that there is a separate path of current flow for each load. Then that circuit is called a parallel circuit.

🟩Note the above two circuits and mention their names, and calculate the total resistance of the two circuit. Assume any value of R1 and R2 but not the value specified in the course.

First I made a series circuit board here. And on the 3 sides of this series circuit, I have placed three resistors of five ohms on the series line. According to the value of resistance, I have shown its value diagram in the physical notebook below.

Then here I made a parallel circuit board. And in this parallel circuit board, I have placed three resistors. And the value of each resistance was 4 ohms. And after placing three resistances on this circuit board as a parallel connection, I have calculated and shown the diagram.

And one thing I learnt earlier is that in series connections the current always increases, and in parallel connections the current always decreases.

🟩Take two pieces of wire and connect them properly. Be sure to mention consistent images and clear descriptions.

Step -01

First, I took a 10mm wire to connect it. And took a wire stripper to peel a wire. And used a nosepliers to fold it. Then I used a wire stripper to strip about 2 inches of wire.

Step -02

Then I held the two wire ends at an angle on either side. Then I divided the copper wire on one side into three parts and took one part. Then I took one-third of the copper from the top side and wrapped it on the other side.

Step -03

Then I divided the rest of the copper wires into equal parts and wrapped them on both sides in the same way as before.

final step

Then, after wrapping my entire copper wire neatly on both sides, I flattened it nicely with nose pliers.

🟩After completing this lesson write what you learn in your own words.

As I have some knowledge of electrical work before, I enjoyed this part a lot today. And I was able to learn a lot of good things by reading and working with my hands. And physically, nothing is ever done by hand; we are always addicted to devices and taking help from others. I feel blessed today by attending this post because I have done a lot of physical work with my hands and pen. Also got a good idea of working on the circuit board.
