Electric Current and Circuits for Class 6

Electric Current and Circuits are an important part of our daily life. From lighting a bulb to running machines, everything around us depends on the flow of electricity. 

Have you ever noticed that when you press a switch, a bulb instantly glows? Or when the power goes off, everything stops working? This happens because of electric current and circuits. This article is a perfect guide for students to understand what is electric current, electric circuits, and their components in a simple way.

What is Electric Current?

An electric current is the flow of electricity. It is a form of energy and hence, it is also known as electrical energy. Electrical energy can be converted into other forms of energy such as light and heat energy.

So, in simple words, it is the movement of electricity from one place to another.

Now, you may ask: how does this flow start? The answer is simple. It starts when we connect a power source like a battery.

Interestingly! The more charges flow, the stronger the current becomes. That’s why devices like heaters use more current than small devices like clocks.

What is an Electric Circuit?

Consider you tried lighting a bulb using a cell, wires, and the bulb. You may have noticed that the bulb glows only when all the parts are properly connected in a loop. If even one wire is loose or disconnected, the bulb does not glow.

So here, the bulb lights up only when the wires, the cell and the bulb form a continuous path. 

From this it can be concluded that the electric current flows only when there is a complete path present to flow between the two terminals of an electric cell. 

This path, along which an electric current can flow, is known as an electric circuit.

Working of an Electric Circuit

When we connect a bulb and a cell using wires to form a closed path, an electric circuit is formed through which an electric current can flow.

When the electric current flows through the filament of the bulb, it heats the filament and the bulb glows.

In an electric circuit, the current flows from the positive terminal to the negative terminal of an electric cell.

Different Components of an Electric Circuit

An electric circuit is made up of different parts that work together to allow electric current to flow. What are the components of an electric circuit? Let’s understand its main components.

• The source of an electric current, such as an electric cell or battery
• An electrical appliance that uses electric current such as a bulb or a mini electric motor (It acts as an indicator for electricity).
• Conducting wires to provide a path for the flow of an electric current
• A switch or a key to control the circuit

And so far, we’ve seen that a complete path is necessary for electricity to flow. This basic understanding helps us explain how everyday electrical devices work.
