How Does It Compare with Other JLab Network Theorem Trainers?
| Trainer | Theorems | DC supply (as listed) | Meters (as listed) |
|---|---|---|---|
| This trainer (EL-VONT-1127) | Superposition, Norton’s, Thevenin’s, maximum power transfer | Three fixed outputs, 12 V and 5 V at 100 mA | Four moving-coil meters |
| Verification of Superposition Theorem | Superposition | Two fixed regulated outputs, 12 V and 5 V at 500 mA | Three moving-coil meters |
| Verification of Maximum Power Transfer Theorem in DC Circuits | Maximum power transfer (DC) | One fixed output, 12 V at 300 mA | Two moving-coil meters |
| Network Theorems (Electronics Lab range) | Superposition, Thevenin’s, Norton’s, maximum power transfer | Fixed regulated 12 V and 5 V DC | Dual-range moving-coil voltmeter and ammeter |
Choose this trainer when one panel should carry all four theorems; the single-theorem trainers suit labs that set up one experiment per bench, and the Network Theorems unit lists dual-range meters and patch cords.
What Is the Network Theorems Trainer Used For?
Network theorems reduce a circuit with several sources and resistors to something simpler to analyse, and this trainer lets students check each theorem against meter readings instead of only on paper. It suits basic electrical engineering and network analysis practicals in engineering and polytechnic diploma courses, B.Sc. physics and electronics labs, and ITI/TVET electrical workshops. Superposition is verified by measuring a branch current with both supplies acting and then with each supply acting alone; Thevenin’s and Norton’s theorems by measuring the open-circuit voltage and short-circuit current at a pair of load terminals and comparing the predicted load current with the measured one; and maximum power transfer by varying the load resistance, typically with a potentiometer, and noting where the power in the load peaks.
Wire each circuit by following the diagram printed on the panel, check meter polarity before switching on, and switch the supplies off before rewiring. Small differences between measured and calculated values come from meter resolution and resistor tolerance.
What to Specify When Ordering
- Quantity — the minimum order is 10 trainers; many labs plan one per bench group.
- One panel or a set — this four-theorem trainer, or the separate superposition, Norton’s, Thevenin’s, reciprocity and maximum power transfer trainers.
- Mains supply and plug type at the destination — the listing does not state the input, so give it in your enquiry.
Frequently Asked Questions
Which theorems can be verified on this trainer?
Four: superposition, Norton’s, Thevenin’s and maximum power transfer. The circuit for each is printed on the front panel, and the supplies, meters, resistances and potentiometers are brought out on terminals for wiring.
What power supplies and meters does it have?
Three fixed-output DC power supplies, listed as 12 V and 5 V at 100 mA, and four moving-coil meters. The listing gives neither the meter ranges nor the voltage of the third output, so ask JLab for these details with your quote.
How is Thevenin’s theorem checked on it?
Measure the open-circuit voltage across the load terminals and the resistance seen from them with the sources replaced by their internal resistance, then compare the load current predicted by the Thevenin equivalent with the current read on the meter. Norton’s theorem uses the short-circuit current at the same terminals in place of the open-circuit voltage.
What result should the maximum power transfer experiment show?
Power in the load rises as the load resistance increases, peaks when the load resistance equals the Thevenin resistance of the source network, and falls after that. At the peak only half of the power drawn from the supply reaches the load, so maximum power transfer is not the same as maximum efficiency.
What information is needed for an export quotation?
Send the quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), the mains voltage the trainers must run on, any packing or labelling needs, and the tender reference if one applies.
Who manufactures this trainer?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, builds it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
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. This trainer is built at JLab’s own works rather than bought in from a trader, so colleges, polytechnics, ITIs, dealers and importers buy it factory-direct, every unit is visually inspected before dispatch, and repeat orders and replacement parts are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Niger in West Africa, Albania in Southern Europe, Congo in Central Africa, Yemen in the Middle East and Peru in South America. Institutions buying through tenders will find details on the JLab lab tenders page.
Other Network Theorem Trainers
- Verification of Nortons Theorem — Norton’s theorem on its own panel, with one 12 V supply, two moving-coil meters and 4 mm sockets.
- Verification of Thevenins Theorem — the matching single-theorem trainer for Thevenin’s theorem.
- Ohms Law Series and Parallel Circuits — the groundwork experiment on Ohm’s law and series and parallel circuits.
