Based on Chapter 12: “What if it finishes…?” from your uploaded Class 5 EVS book, the topic “A Bulb Connected to an Electric Cell” is touched upon in a basic way when discussing electricity, torch, battery, and circuits. Using this, here are 10 one-word answer type questions based on the topic with answers and short explanations included right after each.
One-word Answer Type Questions – A Bulb Connected to an Electric Cell
1. Question: What glows when connected properly to a cell?
• Answer: Bulb
• Explanation: A bulb glows when connected correctly to a cell through wires, completing the circuit.
2. Question: What is the source of electricity for a bulb in a torch?
• Answer: Cell
• Explanation: A torch uses an electric cell to provide electricity for the bulb to glow.
3. Question: What joins the bulb and the electric cell?
• Answer: Wire
• Explanation: Wires are used to connect the terminals of the cell to the terminals of the bulb.
4. Question: What must be complete for the bulb to light up?
• Answer: Circuit
• Explanation: A closed or complete circuit is needed for electricity to flow and make the bulb glow.
5. Question: What is the thin part inside a bulb that gives light?
• Answer: Filament
• Explanation: The filament is a thin wire inside the bulb that heats up and glows when electricity passes.
6. Question: What happens to the bulb if the wires are not connected properly?
• Answer: Off
• Explanation: If the connections are loose or wrong, the circuit is incomplete and the bulb remains off.
7. Question: What part of the electric cell connects to the metal cap of the bulb?
• Answer: Positive
• Explanation: The positive terminal of the cell connects to the bottom point or cap of the bulb to complete the circuit.
8. Question: What part of the bulb touches the base of the torch to form a circuit?
• Answer: Terminal
• Explanation: The bulb has metal terminals that must touch the torch’s metal base to complete the electric path.
9. Question: What is needed along with wires and bulb to make light?
• Answer: Battery
• Explanation: A battery (or electric cell) provides the electric energy needed to light the bulb.
10. Question: What happens to the bulb if the cell is used up?
• Answer: Dim
• Explanation: When the cell’s power reduces, the bulb becomes dim or stops glowing due to low electricity.
