Questions and Answers

What is the effect of the switch being in the 'OFF' position in a circuit?

  • The battery will lose its charge more rapidly.
  • The light bulb will glow dimly due to residual current.
  • The circuit will be incomplete and no current flows. (correct)
  • Current will flow through the entire circuit.

    • Which component of the circuit is primarily responsible for providing electrical energy?

  • The battery (correct)
  • The switch
  • The wires
  • The filament

    • What happens to the filament in a light bulb when electric current passes through it?

  • It generates excess energy that charges the battery.
  • It glows due to the heating effect. (correct)
  • It cools down and stops glowing.
  • It creates a magnetic field.

    Study Notes

    Cell Holders

    • Cell holders connect multiple cells in series to create a battery.
    • Negative terminal of one cell connects to the positive terminal of the next.
    • Holders accommodate different numbers of cells.
    • Cells should be placed with positive terminals aligned.

    Electric Circuits

    • An electric circuit is a complete path for electric current to flow.
    • It includes a battery, wires, a switch, and a bulb.
    • When the switch is 'ON', the circuit is closed, and current flows.
    • When the switch is 'OFF', the circuit is open, and no current flows.

    Switch

    • Controls the flow of current in a circuit.
    • A closed circuit means the switch is 'ON'.
    • An open circuit means the switch is 'OFF'.

    Battery

    • Provides electrical energy for the circuit.

    Bulb

    • Contains a filament that glows when an electric current passes through it.

    Filament

    • A thin wire within the bulb that gets hot and glows when current flows. This is the heating effect of electric current.

    Electric Current and its Effects

    • Electric current can generate heat.
    • This heating effect is used in many appliances, including electric heaters, immersion heaters, hotplates, irons, geysers, electric kettles, and hair dryers.
    • These appliances contain a coil of wire, known as an element, that heats up when current passes through it.
