    The document discusses the components needed to make a light bulb light up, including a bulb, battery, wires, and switch connected in a closed circuit. It explains that electricity can flow through a series circuit when all components are present and connected, but not in a parallel circuit if one bulb fails. Safety precautions are provided for working with electricity, and instructions given for a series circuit experiment using a bulb, battery, wires, and switch.

    Y RULES AND PRECAUTIONS IN USING ELECTR


    1. Do not do an experiment involving an electricity without parent/guardians supervision.
    2. Never touch an open wire with bare hands.
    3. Don’t plug a bunch of staff into one outlet or extension cord.
    4. Don’t yank an electrical cord from the wall.
    5. Avoid octopus connection.
    6. Unplug all electrical appliances when not in use.
    7. Keep electrical stuff far away from water.
    8. Do not touch the switch or plug-ins if any part of your body is wet.
    9. Do not put your fingers into an empty socket or plug-ins.
    10. When using any devices, it is better to unplug or use proper tools
    with plastic or wooden handles before handling them.
