The incandescent bulb E10 3.8V/0.3A is a miniature screw-base lamp used for low-voltage school physics circuits, electrical demonstrations, and STEM experiments. It is suitable for teachers, students, electronics labs, and practical kits where visible lamp glow is required to show current flow and circuit continuity.

Product Description

The Incandescent Bulb 3.8V/0.3A E10 is designed for use with compatible E10 lamp holders and low-voltage classroom power sources. Its visible filament glow helps students understand closed circuits, open circuits, current direction, resistance, and energy conversion from electrical energy to light and heat.

This bulb is useful in practical electricity lessons because the result is immediate and easy to observe. It can be used with batteries, regulated low-voltage DC supplies, switches, plugboards, and test leads, provided the circuit does not exceed the confirmed 3.8V and 0.3A rating.

Key Features

• 3.8V/0.3A electrical rating for compatible low-voltage educational circuits.
• E10 miniature screw base for use with suitable E10 lamp holders.
• Incandescent filament gives a clear visible glow during circuit demonstrations.
• Useful for teaching open circuits, closed circuits, series circuits, and parallel circuits.
• Suitable for school physics labs, electronics classrooms, STEM kits, and teacher demonstrations.
• Works with compatible batteries, power supplies, switches, and circuit boards.
• Compact replacement lamp for repeated student practical activities.
• Simple component for showing electrical energy conversion into light and heat.

How to Use the Incandescent Bulb 3.8V/0.3A E10

1. Check that the lamp holder has an E10 screw socket.
2. Switch off the power source before inserting the bulb.
3. Screw the bulb gently into the holder without overtightening.
4. Connect the lamp holder to a compatible low-voltage circuit.
5. Apply power gradually and observe the bulb glow.
6. Compare brightness if the bulb is used in series or parallel circuits.
7. Switch off power before removing or replacing the bulb.

Safety note: Do not exceed 3.8V/0.3A unless the actual supplied datasheet allows it. Incandescent bulbs become hot during use, so allow cooling before handling.

Care & Maintenance

• Store bulbs in a dry, padded container to prevent breakage.
• Handle the glass envelope carefully and avoid dropping the bulb.
• Do not use bulbs with cracked glass, loose bases, or damaged filaments.
• Keep spare bulbs labelled by voltage and current rating to avoid wrong selection.

Frequently Asked Questions

What is an incandescent bulb E10 used for?

An incandescent bulb E10 is used in low-voltage school circuits to show current flow, circuit continuity, and electrical energy conversion.

What does 3.8V/0.3A mean?

3.8V is the rated operating voltage, and 0.3A is the rated current. The circuit should match these values to avoid premature bulb failure.

Can this bulb be used in school physics labs?

Yes. It is suitable for supervised school physics labs when used with compatible E10 holders and approved low-voltage power sources.

Is this bulb compatible with an E10 lamp holder?

Yes. The bulb has an E10 miniature screw base and should be used with a matching E10 socket.

Can it be used in series and parallel circuits?

Yes. It can be used to compare lamp brightness in series and parallel circuits when the total circuit rating remains safe.

Does the bulb become hot during use?

Yes. Incandescent bulbs produce heat during operation. Let the bulb cool before touching or removing it from the holder.
