Question

question 1-3
sahara wants to build a closed circuit to power a light bulb.
which circuit would allow the electrical energy to flow to light the bulb?

Explanation:

To light the bulb, a closed circuit is needed where the electrical path is complete, allowing current to flow from the battery, through the bulb, and back. The first circuit (with the switch) appears to have a complete path (assuming the switch is closed or the diagram shows a closed circuit setup), while the second likely has an open part (like a disconnected wire or open switch). A closed circuit (continuous loop of conductors connecting the battery, bulb, and any components) enables current flow to power the bulb.

Answer:

The circuit with the battery, light bulb, and the switch (the top - shown circuit with the blue - circled option) is the one that allows electrical energy to flow to light the bulb as it represents a closed circuit (assuming the switch is in a closed state or the wiring forms a complete loop for current to travel from the battery, through the bulb, and back to the battery).
