VR Tour For Std. 6 Ch. 12: Electricity and Circuits
What's Included in Virtual tour of this chapter
Electric cells are the source of electricity. In our day-to-day lives, we use different types of electric equipment which requires a different type of electric cell. We will understand how the current flows and the bulb glows only when the electric circuit provides a complete path for current to flow between both terminals of the electric cell. We have so much fun switching on and off the torchlight but do you know the internal structure of the torch? We will learn that in our Virtual tours. Children will also learn in detail about conductors and insulators. Conductors are materials that allow the free flow of electricity whereas insulators are the materials that restrict the flow of electricity.
Virtual tour 1: Types of electric Cells
In this virtual tour, we will understand how electric cells produce electricity? Chemicals stored inside the cell, produce electricity through internal reactions. Once chemicals are used up, the cell loses its capability to produce electricity. Cells have two terminals: a positive and a negative terminal.
Virtual tour 2: Different types of electric circuit connections
Do you know how the electric bulb gets lit using an electric cell? In the circuit, the wires are connected to both the terminals of the battery. The other ends of wires are connected with the terminals of an electric bulb. This electric circuit provides a complete path for current to flow between the two terminals of the electric cell. So, the current passes and the bulb glows.
Virtual tour 3: Electric Torch and its parts
We will understand the internal structure of a torch. When we switch on the button, a circuit is completed so the current can pass and the bulb glows. Various components of the torch are bulb, spring, wire, slide switch, cells. We will get to know about each component in detail further in the virtual tour.
Virtual tour 4: Electric Conductors
Materials that do not allow an electric current to pass through them are called insulators of electricity. Examples are rubber, wood, plastic, glass, air, cloth, etc. whereas substances that allow the current to flow from them are called conductors of electricity. Examples are an iron nail, key, safety pin, water, human body, etc. Conductors are mainly metallic while insulators are non-metallic.
