To solve the problem of determining whether the light bulbs will light up based on the circuits shown in the image, we need to analyze each circuit and check if there is a complete, unbroken path for the electric current to flow from the battery through the bulb(s) and back to the battery. Here's the step-by-step analysis for each circuit:
---
Circuit 1:
-
Description: The circuit has a battery, a light bulb, and wires connecting them.
-
Analysis: The wires form a continuous loop from the positive terminal of the battery, through the light bulb, and back to the negative terminal of the battery. There are no breaks in the circuit.
-
Conclusion: The light bulb will light up.
---
Circuit 2:
-
Description: The circuit has a battery, a light bulb, and wires. However, the wires do not connect the battery to the light bulb.
-
Analysis: The wires are not connected to the battery terminals, so there is no path for the current to flow through the bulb.
-
Conclusion: The light bulb will not light up.
---
Circuit 3:
-
Description: The circuit has a battery, two light bulbs, and wires. The bulbs are connected in series (one after the other).
-
Analysis: The wires form a continuous loop from the positive terminal of the battery, through both light bulbs, and back to the negative terminal of the battery. There are no breaks in the circuit.
-
Conclusion: Both light bulbs will light up.
---
Circuit 4:
-
Description: The circuit has a battery, a light bulb, and wires. However, the wires are not connected to the battery terminals.
-
Analysis: The wires are not connected to the battery terminals, so there is no path for the current to flow through the bulb.
-
Conclusion: The light bulb will not light up.
---
Circuit 5:
-
Description: The circuit has a battery, a light bulb, and wires. The wires form a closed loop.
-
Analysis: The wires form a continuous loop from the positive terminal of the battery, through the light bulb, and back to the negative terminal of the battery. There are no breaks in the circuit.
-
Conclusion: The light bulb will light up.
---
Circuit 6:
-
Description: The circuit has a battery, a light bulb, and wires. However, one of the wires is disconnected, breaking the loop.
-
Analysis: The wire is not connected to the battery terminal, so there is a break in the circuit, and no current can flow through the bulb.
-
Conclusion: The light bulb will not light up.
