Semiconductors Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12570
Jlab Export is a leading Semiconductors Manufacturer,and suppliers in India
Semiconductors (code EL-PL-12570) is a set of component panels for studying sensors and semiconductor devices: thermal and photo resistors, a thermo element, a photo-cell, a diode and p-n-p and n-p-n transistors, each on its own small board marked with its circuit symbol. The boards interconnect, and printed instructions come with them. JLab makes the set in Ambala, India.

What Each Panel Shows
An NTC thermal resistor loses resistance as it warms, so a fingertip held on it is enough to raise the current through it; a photo resistor behaves the same way as more light falls on it. The thermo element gives a small voltage when one junction is heated relative to the other, and the photo-cell produces a current from light. The diode conducts in one direction only, which shows at once when its connections are reversed. The p-n-p and n-p-n transistors let a small base current control a much larger collector current, and the two types need opposite supply polarities.
Building Circuits from the Boards
Because each board carries its component’s symbol, students can lay the panels out to match a circuit diagram and join them into a loop with a supply and a meter, then swap one sensor for another without rewiring the rest.
