Simple Circuit Module LED Board Red

Product Code : SLE/PHY/85

Simple Circuit Module LED Board Red (Product Code: SLE/PHY/85) is a board-mounted red light-emitting diode used to show whether current is flowing in simple circuits built during school physics lessons. Its large LED is already wired to a 220 ohm series resistor, so pupils can connect it across potential differences of up to 6 V without adding their own protective resistor. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its Simple Circuit Modules range.

What Is the Red LED Board Used For?

The red LED board acts as a clear visual indicator in series and parallel circuit work: when it glows, pupils know current is passing through that branch. Because a diode conducts in one direction only, reversing the board in a circuit is also a simple way to introduce polarity before students meet the diode symbol on paper. It fits naturally into a school electricity experiment kit alongside switch, motor and sensor modules from the same series.

Keep the supply at or below 6 V, since the fitted resistor is matched to that range. Using the red board together with the green version lets a class build a two-colour indicator, for example to show which of two switches is closed. Store the modules dry and check each connection is firm before a practical begins.

What to Specify When Ordering

  • LED colour: this listing is the red board; the green board is a separate item.
  • Number of boards needed per student group or per laboratory.
  • Other Simple Circuit Modules (push switch, motor, light-dependent resistor) to include in the same order.
  • The supply you plan to use, keeping within the 6 V limit of the board.

Frequently Asked Questions

What voltage is the Simple Circuit Module LED Board Red designed for?
The Simple Circuit Module LED Board Red is intended for potential differences of up to 6 V. Its large red LED already has a 220 ohm series resistor fitted, so within that limit it can be connected straight into a low-voltage school circuit.

Why does the red LED board have a series resistor?
The series resistor on the Simple Circuit Module LED Board Red limits the current through the diode. An LED joined directly to a cell can draw too much current and fail, so the fitted 220 ohm resistor protects it during pupil experiments.

Will the red LED board light if it is connected the wrong way round?
No. An LED conducts in one direction only, so the Simple Circuit Module LED Board Red stays dark when its connections are reversed. Teachers often use this to introduce polarity; swapping the connections makes the board light again.

Who supplies the Simple Circuit Module LED Board Red?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, supplies the Simple Circuit Module LED Board Red from Ambala, Haryana, India. The company sources the board together with the rest of the Simple Circuit Modules range and quotes it to schools, dealers and importers.

What should a quotation request for the red LED board include?
A quotation request for the Simple Circuit Module LED Board Red should state the quantity, whether you also need the green board or other Simple Circuit Modules, and the delivery location. Send these details through our contact page for a reply.

Can the Simple Circuit Module LED Board Red be ordered in bulk for export?
Yes. The Simple Circuit Module LED Board Red can be ordered in class-set or bulk quantities for schools and distributors in India and international markets. Share the quantity and destination, and ScienceLab will confirm packing and shipping options with the quotation.
