Components of a simple circuit worksheet - Free Printable

Explanation:
We are given four circuit components: Battery, Wire, Switch, and Bulb.
There is a simple circuit diagram with four blank boxes — each box should be labeled with one of the components.

Let’s trace the circuit path (following the red arrows):

1. The circuit starts at the Battery (the tall rectangle with + and lightning symbol). One end of the battery connects to a wire that goes to the Switch (the ON/OFF button).
2. From the switch, a wire goes to the Bulb (the glowing light bulb).
3. From the bulb, a wire returns to the other terminal of the Battery, completing the loop.
4. The lines connecting everything are Wires.

Now look at the four empty boxes:

- Box on the right side of the battery → This connects directly to the battery’s positive (+) terminal. In a standard drawing, this is where the Wire starts going toward the switch. But actually, looking carefully: the box *next to the battery* (on its right) is connected to the top of the battery — that’s just the battery’s own terminal; however, the blank boxes are meant to label the *components*, not the wires themselves.

Wait — let’s match each blank to the component it represents in the diagram:

- The bulb has a blank box to its left → that box should be labeled Bulb (since it's pointing to the bulb).
- The battery has a blank box to its right → that box should be labeled Battery.
- The switch has a blank box below it → that box should be labeled Switch.
- There’s one more blank box above the wire between bulb and battery → that must be the Wire, since wires connect everything.

But actually, in such drag-and-drop diagrams, each blank is placed *next to* or *pointing to* a component, and you label the component.

Looking at positions:
- Left of bulb → points to bulb → label: Bulb
- Right of battery → points to battery → label: Battery
- Below switch → points to switch → label: Switch
- Above the curved red line (the connection from bulb back to battery) → that’s the Wire

Yes — all four components are used once.

So the correct labeling is:
- Box left of bulb → Bulb
- Box right of battery → Battery
- Box below switch → Switch
- Box above the red curved line (connecting bulb to battery) → Wire

Final Answer:
Bulb, Battery, Switch, Wire
