Looking at the image, I can see it’s a worksheet titled “Electric Circuits and Electric Current” with four diagrams showing different circuit setups. Each diagram has a question asking whether the bulb will light up or not.
Let me go through each one carefully:
Top Left Diagram:
- There’s a battery (cell), a switch, and a bulb.
- The switch is drawn in the open position (not connected).
- For a bulb to light, the circuit must be complete — meaning electricity must be able to flow from the battery, through the bulb, and back to the battery.
- Since the switch is open, the circuit is broken → no current flows → bulb will NOT light.
Top Right Diagram:
- Battery, switch, and bulb are present.
- The switch is closed (connected).
- Wires connect all components in a loop.
- This is a complete circuit → current can flow → bulb WILL light.
Bottom Left Diagram:
- Battery, switch, and bulb.
- Switch is open again.
- Even though wires are connected, the open switch breaks the circuit → no current → bulb will NOT light.
Bottom Right Diagram:
- Battery, switch, and bulb.
- Switch is closed.
- All connections look complete.
- Circuit is closed → current flows → bulb WILL light.
So, summarizing:
- Top left: No
- Top right: Yes
- Bottom left: No
- Bottom right: Yes
Final Answer:
Top left: No
Top right: Yes
Bottom left: No
Bottom right: Yes
