Jlab Export is a leading Study the effect of negative feed back of transistor amplifier Manufacturer,and suppliers in India
Study the effect of negative feed back of transistor amplifier (code EL-AK-1121) is a trainer for studying how negative feedback changes three properties of a transistor amplifier: its voltage gain, input resistance and output impedance. The listing names these measurements but not the circuit hardware, so confirm the details with JLab before ordering. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Negative Feedback Amplifier Trainer Used For?
Negative feedback returns part of an amplifier’s output to its input in opposition to the input signal. With the feedback disconnected and then connected, the voltage gain falls, but it becomes steadier and less dependent on the transistor, the bandwidth widens and distortion drops. How the input and output resistance change depends on how the feedback is connected, which is why both are measured. The experiment is part of analog electronics practicals in B.Sc. physics and electronics, diploma and engineering courses and ITI/TVET electronics trades, and is usually run with a sine-wave signal source and an AC millivoltmeter or oscilloscope.
Frequently Asked Questions
What does negative feedback do to the voltage gain?
It reduces it. The gain with feedback equals the gain without feedback divided by one plus the loop gain, so a large loop gain makes the result depend mainly on the feedback network rather than on the transistor.
Does negative feedback raise or lower the input resistance?
It depends on the connection. Feedback applied in series with the input raises the input resistance, while feedback applied in shunt lowers it; sampling the output voltage lowers the output impedance, and sampling the output current raises it.
What hardware and instruments come with this trainer?
Neither is described in this listing. Ask JLab for the transistor, supply, meter and connection details, and say if you also need a signal generator, AC millivoltmeter or oscilloscope.
Who manufactures it?
Jain Laboratory Instruments Pvt Ltd (JLab), at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electronics trainers, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. It is built at JLab’s own works, not bought from a trader, so colleges, dealers and importers order factory-direct, and each unit is visually inspected before dispatch. JLab exports worldwide and ships to buyers in every region — for example the Philippines in Southeast Asia, Uzbekistan in Central Asia, Bulgaria in Eastern Europe, Japan in East Asia and France in Western Europe. See the JLab lab tenders page for tender purchases.
