Circuit Components
Power Source
Dry Cell (DC Voltage Source)
Provides electrical energy to the circuit. Converts chemical energy to electrical energy.
Switch
Controls current flow (Open/Closed)
A mechanical device that opens or closes the circuit to control the flow of current.
Light Bulb
Load & Visual Indicator
Converts electrical energy into light and heat. Acts as a resistor in the circuit.
Conducting Wires
Current Pathway (Copper)
Provides a path for electrons to flow. Made of conductive materials like copper.
Instructions
- Click the "Toggle Switch" button or click directly on the switch in the diagram to open/close the circuit.
- When the circuit is closed, current flows and the bulb lights up.
- When the circuit is open, no current flows and the bulb remains off.
- Change the voltage to see how it affects current (Ohm's Law: I = V/R).
- Hover over components to learn more about their function.
