IV. Long Answer Type Questions

  1. Draw a simple electrical circuit and label the parts. Explain how we can connect a bulb in a circuit and how it can show us if an electric current is flowing in the circuit or not.

    Answer: To create a simple circuit:
  • Connect the positive terminal of the cell to one side of the bulb using a wire.
  • Connect the other terminal of the bulb to a switch.
  • Connect the switch back to the negative terminal of the cell.
    If the switch is closed (ON), the bulb glows. This means electric current is flowing. If the switch is open (OFF), the bulb does not glow, showing no current flow.

2. Using a bulb, cell and key, draw diagrams and explain the flow of electric current in an ‘open circuit’ and in a ‘closed circuit’.

Ans: Closed Circuit (Bulb Glows)

In a closed circuit, the key or switch is in the closed position. This means the circuit is complete, and electric current flows from the positive terminal of the cell, through the key and the bulb, and returns to the negative terminal. As a result, the bulb receives current and glows.

Class 6 Science Chapter 14 Electricity and Circuit - cosed circuit series connection

Open Circuit (Bulb Does Not Glow)

In an open circuit, the key or switch is in the open position. This breaks the path of the current, so the electric current cannot flow through the circuit. Since the bulb does not receive any current, it does not glow.

3. What is a dry cell? What is inside it? Why is it useful to us?
Ans: A dry cell is a type of electric cell that provides a small amount of electricity for use in portable devices. It is called “dry” because it does not contain a free-flowing liquid; instead, it uses a moist paste as the electrolyte.

What is Inside a Dry Cell?

A dry cell consists of:

  • A zinc container (which acts as the negative terminal)
  • A carbon rod in the center (positive terminal)
  • A paste of ammonium chloride and zinc chloride as the electrolyte
  • Manganese dioxide surrounding the carbon rod, which acts as a depolarizer
Class 6 Science Chapter 14 Electricity and Circuit - dry cell

A dry cell is useful because:

  • It is small, portable, and easy to use
  • It does not spill, unlike liquid cells
  • It can be used in everyday devices like wall clocks, remote controls, torches, and toys

Dry cells provide a convenient and safe source of electricity for many household and electronic items.

4. How does an electric torch work? Explain with the help of a diagram.

Answer: An electric torch (also called a flashlight) is a portable device that produces light using electric current. It contains one or more dry cells (batteries), a bulb, a switch, and metal contacts or wires to form an electric circuit.

    Working of an Electric Torch:

    1. Battery (Dry Cell) provides the electrical energy.
    2. Wires or metal strips connect the positive and negative terminals of the battery to the bulb.
    3. Switch is used to open or close the circuit.
    4. Bulb glows when electric current flows through it.
    • When the switch is ON, the circuit becomes closed, allowing current to flow from the battery to the bulb.
    • The bulb receives current and produces light.
    • When the switch is OFF, the circuit becomes open, so no current flows, and the bulb does not glow.


    5. One class of materials allow the flow of electric current and some do not. What are these different classes of material called?

    Answer: The different classes of materials based on their ability to conduct electric current are called:

    1. Conductors
    2. Insulators

    *Conductors are materials that allow electric current to flow through them easily.
      These materials have free electrons that move and carry current.
       Examples: Copper, aluminium, iron, graphite.

    *Insulators are materials that do not allow electric current to pass through them.
      They resist the flow of electricity and are used for safety.
      Examples: Rubber, plastic, wood, glass.

    Summary:

    • Conductors = allow current to flow
    • Insulators = block current flow

    These properties help us in designing safe and effective electrical devices.
