Incandescent Bulb

Product Code : SCL-EI-10608

Lab Glassware Manufacturer, based in Ambala, Haryana, India, has been manufacturing and exporting laboratory, scientific and educational equipment since 1982. The Incandescent Bulb E10 3.8V/0.3A is supplied to school and college physics laboratories and export buyers across the Pacific Islands, including Fiji, Papua New Guinea, Solomon Islands and Vanuatu, for basic circuit teaching.

Quick answer: The Incandescent Bulb E10 3.8V/0.3A is a miniature screw-base lamp that gives a visible glow in low-voltage school circuits, used to demonstrate current flow, open and closed circuits, series and parallel brightness comparisons, and the conversion of electrical energy into light and heat.

Key Features

• 3.8V/0.3A electrical rating for compact 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

Applications / Uses

• Demonstrating current flow in simple school circuits
• Using with E10 lamp holders in electricity experiments
• Comparing bulb brightness in series and parallel circuits
• Showing electrical energy conversion into light and heat
• Using with low-voltage batteries and laboratory DC power supplies

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

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

Completing the Circuit-Building Station

Schools building an entry-level electricity station often pair the Incandescent Bulb E10 3.8V/0.3A with the Lamp Holder on Base E10 for a mounted socket, the Battery Flat 4.5V as a compact power source, and a Universal Plugboard for building and rearranging circuits quickly.

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.
