Question

Look at the diagram. Emily needs to complete the circuit. What two points should be connected to complete the circuit and make the bulb glow?

Answer 1

C) Points 2 and 4

Step-by-step explanation:

In a complete electric circuit, wires carry the current from the battery to the bulb and from the bulb to the battery. The wires should be attached to points 2 and 4 to make the bulb glow.

Answer 2

The points 2 and 4 should be connected.

Step-by-step explanation:

To complete the circuit, we need to connect the two points which when connected, encompass the battery and the bulb in the circuit. The points 2 and 4 do the job, since they connect the terminal of the battery and the terminal of the bulb, and thus complete the circuit.

Therefore, the choice C is correct.
