Verification of Reciprocity Theorem Manufacturer,Supplier and Exporter in India
Product Code : EL-VONT-1132
Jlab Export is a leading Verification of Reciprocity Theorem Manufacturer,and suppliers in India
Verification of Reciprocity Theorem (code EL-VONT-1132) is a trainer for showing that, in a linear resistor network with one source, swapping the positions of the source and the measured current leaves that current unchanged. It has one fixed 12 V DC supply at 300 mA, two moving-coil meters and a circuit diagram printed on the front panel. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Network Theorem Trainers?
| Trainer | Theorem(s) | Supply (as listed) | Meters and extras (as listed) |
|---|---|---|---|
| This trainer (EL-VONT-1132) | Reciprocity | 12 V at 300 mA | Two moving-coil meters |
| Verification of Maximum Power Transfer Theorem in DC Circuits | Maximum power transfer | 12 V at 300 mA | Two moving-coil meters; potentiometer |
| Verification of Superposition Theorem | Superposition | 12 V and 5 V at 500 mA | Three moving-coil meters |
| Verification of Network Theorems | Superposition, Norton’s, Thevenin’s, maximum power transfer | Three outputs, 12 V and 5 V at 100 mA | Four moving-coil meters; potentiometers |
Reciprocity is not among the theorems listed for the four-theorem panel, so this trainer is the one to order where the reciprocity theorem is part of the syllabus. It is listed with the same supply rating and meter count as the maximum power transfer trainer.
What Is the Reciprocity Theorem Trainer Used For?
The reciprocity theorem is taught with the other network theorems in basic electrical engineering, circuit theory and polytechnic diploma courses, and in B.Sc. physics and electronics and ITI/TVET electrical labs. It holds for networks of linear, bilateral elements such as resistors with a single independent source: if the source in one branch drives a certain current in a second branch, the same source moved into the second branch drives the same current in the first. The ratio of source voltage to that current, the transfer resistance, is the same in both directions.
On this trainer, students connect the 12 V supply in the first position and read the current in the second branch, then interchange the supply and the ammeter and read again; the two currents should agree within meter accuracy. The match is closest when the supply’s internal resistance and the ammeter’s resistance are small compared with the network resistances. Switch the supply off before moving any connection.
What to Specify When Ordering
- Number of trainers — the minimum order is 10.
- Any companion trainers for the same practical cycle, such as superposition, Thevenin’s, Norton’s or maximum power transfer.
- Connecting leads and the mains voltage at the destination.
Frequently Asked Questions
What does the reciprocity theorem say?
In a linear, bilateral network with one source, the current produced in one branch by a source in another branch stays the same when the source and the point of measurement are interchanged.
Does the theorem apply to every circuit?
No. It needs linear, bilateral elements and a single independent source; it does not hold for circuits containing diodes or other one-way devices, or dependent sources.
What supply and meters are built in?
One fixed-output DC supply of 12 V at 300 mA and two moving-coil meters, with the supply, meters and resistances brought out on terminals. Meter ranges and resistor values are not listed; ask JLab for them.
What should I include in an export enquiry?
Quantity, destination country and port or city, delivery terms such as FOB or CIF, the mains voltage, packing or labelling requirements, and the tender reference if the purchase is through a tender.
Who manufactures this trainer?
Jain Laboratory Instruments Pvt Ltd, known as JLab, at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electrical and electronics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The reciprocity trainer is made at JLab’s own works, not resold from a trader, so teaching institutions, dealers and importers buy direct from the factory; every unit is visually inspected before dispatch, and repeat orders and spares are handled by the manufacturer. JLab holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise and Importer-Exporter Code 3317504552. It exports worldwide and ships to buyers in every region — for instance Bahrain in the Middle East, Uruguay in South America, Tonga in Oceania, Belgium in Western Europe and Tajikistan in Central Asia. Tender information is on the JLab lab tenders page.
