Electricity Worksheets - Free Printable

It looks like you've uploaded a worksheet titled "LIGHT BULB ANATOMY", which asks students to label the parts of an incandescent light bulb using a provided word bank. The image shows a diagram of a light bulb with blank lines pointing to various parts, and the word bank includes:

- base
- contact
- glass support
- stem
- filament
- connecting and supporting wires

Let's go step by step to solve this labeling task.

Step 1: Understand the structure of an incandescent light bulb

An incandescent light bulb works by passing electricity through a thin wire (the filament) until it heats up and glows. The main components include:

1. Base – The bottom part that screws into a socket.
2. Contact – The metal point at the bottom center of the base that connects to the electrical circuit.
3. Filament – The thin wire inside the bulb that glows when heated.
4. Glass support – Holds the filament in place and is usually connected to the glass envelope.
5. Stem – The central support structure that holds the filament and wires.
6. Connecting and supporting wires – Wires that connect the filament to the base contacts.

Step 2: Match each label to the correct part in the diagram

Looking at the diagram (based on standard light bulb anatomy):

- The base is the threaded bottom part where the bulb screws into the fixture.
- The contact is the small metal dot at the very bottom center of the base.
- The filament is the coiled wire inside the bulb that glows.
- The glass support is the structure near the top of the bulb that supports the filament.
- The stem is the central column inside the bulb that connects the filament to the base.
- The connecting and supporting wires are the wires running from the filament down to the base.

Step 3: Label the diagram

Here’s how the labels should be matched:

1. Base → The screw-in bottom part.
2. Contact → The small metal tip at the bottom center of the base.
3. Filament → The coiled wire inside the glass bulb.
4. Glass support → The glass piece near the top that holds the filament.
5. Stem → The central black tube extending from the base upward.
6. Connecting and supporting wires → The wires running from the filament down to the base.

Final Answer (Labels for the Diagram)

- Line pointing to the bottom screw-in part: base
- Line pointing to the small metal dot at the bottom center: contact
- Line pointing to the coiled wire inside the bulb: filament
- Line pointing to the glass piece near the top: glass support
- Line pointing to the central black tube: stem
- Line pointing to the wires connecting filament to base: connecting and supporting wires
