A simple circuit with a switch, battery, and lightbulb can be described using the following components:

1. A Battery: Provides the electrical voltage to power the circuit.
2. A Lightbulb: Serves as the load, converting electrical energy into light.
3. A Switch: Controls the flow of electrical current, turning the lightbulb on or off.

Here’s a simple textual description of how you’d connect them:

1. Connect one terminal of the battery to one terminal of the switch using an electrical wire.
2. Connect the other terminal of the switch to one terminal of the lightbulb.
3. Finally, close the circuit by connecting the other terminal of the lightbulb back to the remaining terminal of the battery.

When the switch is closed (or “on”), it completes the circuit, allowing current to flow from the battery through the lightbulb, lighting it up. When the switch is open (or “off”), the circuit is broken, and the lightbulb turns off.
