Product Code : SCL-EI-10629
The Red LED with Series Resistor is an educational circuit indicator used for demonstrating current flow, polarity, resistance, and LED protection in school physics and electronics experiments. It is intended for students, teachers, laboratory technicians, and STEM trainers who need a safe visual output component for supervised low-voltage circuit learning.
Product Description
The Red LED with Series Resistor helps students see when a circuit is complete and correctly connected. The LED gives a visible red light output, while the series resistor limits current and helps protect the LED from excessive current in suitable low-voltage teaching circuits.
This product is suitable for Physics Lab Equipment, Electronic Instruments, plug-in circuit boards, school electricity kits, and STEM electronics demonstrations. The final LED voltage rating, resistor value, current rating, connector type, and board compatibility should be confirmed before publication or tender submission.

- Protective packing for safe storage and transport
- Optional plug-in board, connecting leads, switches, cells, meters, or activity guide only if specified in the order
Applications / Uses
- Demonstrating LED indication in school physics circuits.
- Teaching polarity and correct current direction in basic electronics.
- Showing how a resistor limits current in a simple LED circuit.
- Observing open-circuit and closed-circuit conditions visually.
- Using with switches, cells, meters, and plug-in training boards.

How to Use the Red LED with Series Resistor
- Check the confirmed voltage and current rating before connecting the component.
- Insert or connect the LED element into the compatible circuit board or teaching setup.
- Connect the LED in the correct polarity as shown in the circuit diagram.
- Connect the power source, switch, and meter if required by the experiment.
- Apply the recommended low-voltage supply and observe the red light output.
- Disconnect the power supply before removing or changing the component.
Safety note: Do not exceed the confirmed electrical rating. The series resistor helps limit current, but the component should still be used only with correctly rated low-voltage circuits.
Care & Maintenance
- Store the LED element in a dry, labelled component box after use.
- Keep terminals clean, dry, and free from dust or corrosion.
- Do not bend connectors or force the component into an incompatible board.
- Replace the unit if the LED does not glow, the resistor is burnt, or the connector is loose.

Frequently Asked Questions
What is a Red LED with Series Resistor used for?
A Red LED with Series Resistor is used as a visible indicator in school physics and electronics circuits. It helps students observe current flow, polarity, and circuit completion.
Why is a series resistor used with an LED?
A series resistor limits current through the LED. This helps protect the LED from excessive current when it is used with a compatible low-voltage supply.
Is this component suitable for school students?
Yes. It is suitable for supervised school and STEM experiments when connected to a correctly rated low-voltage circuit.
Does LED polarity matter?
Yes. An LED is polarity-sensitive and should be connected according to the circuit diagram. If connected in reverse, it may not glow.
What resistor value is included?
The resistor value should be confirmed before publication or purchase. The final value must match the intended voltage supply and experiment design.
What details should be confirmed before purchase?
Confirm LED rating, resistor value, voltage rating, current rating, connector style, compatible board type, quantity, and whether accessories are included.
