Materials Required

Before starting your project, gather the following materials:

Step-by-Step Guide to Making a Light Bulb

Follow these steps carefully to create your light bulb:

Step 1: Prepare the Filament

Cut a piece of filament wire about 10 cm long. Strip about 1 cm of insulation from both ends if using insulated wire.

Step 2: Create Connections

Attach one end of the filament wire to the positive terminal of your power source using electrical tape. Ensure a strong connection.

Step 3: Insert the Filament

Carefully insert the filament into the glass container. Make sure it does not touch the sides of the container, which could cause a short circuit.

Step 4: Secure the Power Source

Connect the other end of the filament wire to the negative terminal of the power source using more electrical tape. Ensure everything is secure.

Step 5: Test Your Light Bulb

Once everything is connected, turn on the power source. The filament should glow, creating light. If it doesn’t work, double-check your connections.
