What Is the Voltage and Current Feedback Amplifier Trainer Used For?
Feedback is one of the central ideas of analogue electronics, and this trainer is used to teach it in B.Sc. electronics and physics, engineering, polytechnic and ITI/TVET labs. Negative feedback returns part of the output to the input. It lowers the gain but makes it stable and set by resistor values rather than by the op amp itself, and it widens the bandwidth and reduces distortion.
What the feedback senses decides the result. With voltage feedback, a fraction of the output voltage is fed back — the non-inverting amplifier is the classic example — so the output voltage is held steady and the output impedance is low. With current feedback, the signal fed back is proportional to the load current, sampled across a resistor in series with the load, so the output current is held steady against changes in load and the output impedance is high. Students wire each arrangement through the front-panel sockets, take readings on the two meters, and compare gain and load behaviour. Here “current feedback” refers to this feedback arrangement, built around the IC 741.
What to Specify When Ordering
- Quantity — the minimum order is 10 trainers.
- Meter ranges — the two meters are dual range; ask for the ranges if your experiment sheets specify them.
- Companion trainers — the inverting and non-inverting amplifier and V to I converter trainers cover related experiments.
Frequently Asked Questions
What does this trainer demonstrate?
The op amp used as a voltage feedback amplifier and as a current feedback amplifier, so students can compare how each type of negative feedback affects gain, output impedance and load regulation.
What is the difference between voltage and current feedback?
Voltage feedback samples the output voltage and keeps it steady, giving a low output impedance. Current feedback samples the load current and keeps it steady, giving a high output impedance.
Which op amp and supply are fitted?
An IC 741 connected inside the trainer, with a +15 V DC regulated power supply.
What meters are included?
Two round meters of dual range. The listing does not give their ranges, so ask JLab if you need them.
What should an export enquiry include?
Quantity, destination country and port or city, delivery terms such as FOB or CIF, packing or labelling needs and any tender reference.
Who manufactures this trainer?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of electronics trainers and laboratory instruments in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This feedback amplifier trainer is assembled at JLab’s own works rather than bought from a trader, so colleges, universities, dealers and importers buy it factory-direct, each unit is checked visually before dispatch, and repeat orders go back to the maker. JLab exports worldwide and ships to buyers in every region — for example Japan in East Asia, Ireland in Western Europe, Bulgaria in Eastern Europe, Trinidad and Tobago in Central America and the Caribbean and Finland in Northern Europe. Tender information is on the JLab lab tenders page.
