How Does It Compare with Other JLab Resistance Circuit Boards?
| Model | Experiments | Listed features |
|---|---|---|
| This apparatus (EL-VOVLACOS-1102) | Properties of resistances in series and parallel | Two moving coil meters (voltage and current); printed series and parallel diagram; resistances mounted along the circuit |
| Ohm’s Law Apparatus | Verification of Ohm’s law (V = IR) | Two moving coil meters; one wire-wound potentiometer; terminals for a 6 V battery and a wire-wound resistance |
| Ohms Law Series & Parallel Circuits | Ohm’s law, series circuits and parallel circuits | Built-in continuously variable regulated DC power supply |
Choose this apparatus when the practical is specifically about how resistances combine; the Ohm’s law board suits the V = IR experiment, and the combined series and parallel board suits labs that want Ohm’s law and both combinations on one unit with its own supply.
What Is the Series and Parallel Resistance Apparatus Used For?
In a series connection the same current flows through every resistance, the voltages across them add up to the supply voltage, and the equivalent resistance is the sum of the individual values. In parallel, every branch has the same voltage, the branch currents add up to the total, and the reciprocal of the equivalent resistance is the sum of the reciprocals, so the combination is smaller than the smallest resistance. Students wire each arrangement following the printed diagram, read voltage and current on the two meters, calculate the resistance from the readings and compare it with the expected value. This is a standard activity in the class 10 electricity chapter and in senior physics practicals, and the apparatus also serves first-year college, polytechnic and ITI electrical labs as an Ohm law experiment kit for combinations of resistors.
Switch off the supply before changing connections, and start with the meters on a suitable range so the needles do not swing past full scale.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; many schools plan one per student pair or group.
- Power source — the listing does not name a power supply, so state whether you need a battery eliminator or DC supply quoted with it.
- Companion apparatus — the Ohm’s law board or a digital multimeter can be added to the same enquiry.
Frequently Asked Questions
What experiments can be done with this apparatus?
Verification of the properties of resistances connected in series and in parallel: equal current and added voltages in series, equal voltage and added currents in parallel, and the equivalent resistance of each combination.
What meters are fitted?
Two moving coil meters, one to measure voltage and one to measure current. Their ranges and the resistance values are not stated in the listing, so ask JLab for them with your quotation.
Is a power supply included?
A power supply is not mentioned in the listing. Ask JLab whether one is supplied, or add a suitable DC source to your enquiry.
What is the size of the apparatus?
It measures 10 x 8 x 3 inches (about 25 x 20 x 8 cm).
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of physics and electrical lab apparatus, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. The apparatus is assembled at JLab’s own works, not sourced from a trader, so schools, colleges, dealers and importers buy it factory-direct; every unit is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Slovakia in Eastern Europe, Panama in Central America and the Caribbean, Congo in Central Africa, Tanzania in East Africa and Sudan in North Africa. The JLab lab tenders page covers tender supply.
