Current Indicator LED Manufacturer,Supplier and Exporter in India

The Current Indicator LED (Product Code: SLE/CH/117) is a light-emitting diode indicator used to show, at a glance, whether an electric current is flowing in a circuit. In a chemistry classroom it is most often connected in series with a solution or a simple cell, so students can see immediately whether a liquid conducts or whether a cell is producing current. It is a simple companion to any electrochemical cell kit school laboratories use, and it is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Key Details

Typical Use

A common practical places the indicator in series with a low-voltage supply and a pair of electrodes dipped into different liquids. Tap water, salt solution, sugar solution and dilute acid can be tested in turn: where the LED lights, the liquid contains mobile ions and conducts; where it stays dark, it does not. Comparing how brightly the indicator glows gives a quick, qualitative sense of stronger and weaker electrolytes before students move on to measured readings with a meter. The same indicator can confirm that a home-made cell, such as two different metals in an electrolyte, is actually delivering current.

Like all LEDs, the indicator conducts in one direction only, so if it fails to light in a working circuit, reverse the connections before assuming there is no current. Use low-voltage supplies, keep connections dry and away from the liquid being tested, and rinse the electrodes between samples to avoid carry-over. It is a handy first step before setting up the electrolysis apparatus India schools use for decomposing solutions, because it shows students that current is flowing before products begin to form.

Frequently Asked Questions

What does the Current Indicator LED show?
It lights up when current flows through the circuit it is connected to, giving a clear yes-or-no signal for conductivity and cell tests.

What operating voltage and current does it need?
The electrical ratings are not published in our current product notes. Please request them through our contact page so you can match the indicator to your power source.

Why doesn’t it light even though the circuit is complete?
An LED only conducts in one direction. Swap the two connections; if it still stays dark, check the supply and the electrode contacts.

Does it have built-in current limiting?
This is not stated in our documentation. Confirm with us before connecting it directly to a supply without a series resistor.

Can it tell strong and weak electrolytes apart?
Only roughly, through differences in brightness. For measured values, use an ammeter or conductivity meter alongside it.

Can you supply class quantities or export orders?
Yes. We quote class sets and larger orders for schools and distributors in India and international markets.
