About the Electric Circuit 3D model (Physics)

A working series circuit — battery, switch, wires and a glowing bulb you can inspect part by part.

A circuit needs a complete loop for current to flow. The battery provides the voltage that pushes charge, the wires carry it with very little resistance, the switch opens or closes the loop, and the bulb converts electrical energy into light and heat.

What students learn from this physics model

• Identify the components of a simple series circuit
• Explain why a circuit must form a complete loop
• Describe the energy change that happens in the bulb

Labelled parts explained

What is the Battery in Electric Circuit?

A battery converts chemical energy into electrical energy, creating the potential difference (voltage) that pushes charge around the circuit.

What is the Bulb in Electric Circuit?

Current heats the thin filament until it glows. The bulb also acts as a resistor, limiting the current in the circuit.

What is the Switch in Electric Circuit?

A closed switch completes the loop so current can flow. An open switch breaks the loop and the bulb goes out.

What is the Wire in Electric Circuit?

Copper wires carry charge with very little resistance, connecting every component into a complete loop.
