Resistance Coil Unit
Product Code : SCL-EAE-11262
Quick answer: The Resistance Coil Unit is the resistive element for low-voltage physics circuits. With a regulated supply, ammeter and voltmeter it shows how a resistance limits current and develops a measurable potential difference, and several units can be joined to find equivalent resistance in series and parallel. The value is selected for the experiment. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
When a current I passes through a resistance R, a potential difference V = IR appears across it. The resistance coil unit makes this measurable: students set the supply, read the current on an ammeter in series and the potential difference on a voltmeter in parallel, and confirm that V/I stays constant for a fixed resistance at steady temperature.
- Check the stated resistance, current and power ratings before use.
- With the supply off, connect the supply, key, rheostat, ammeter and resistance unit in series.
- Connect the voltmeter across the unit terminals.
- Switch on and take several V and I readings by moving the rheostat.
- Join two units in series and then in parallel, and compare the measured equivalent resistance with the calculated value.

Frequently asked questions
How is the resistance coil unit different from a resistance box?
A resistance box offers many selectable values; the resistance coil unit provides one defined resistance for a circuit, and further units are added to build combinations.
Can several resistance coil units be combined?
Yes. When matching units are available they can be joined in series or parallel to study equivalent resistance.
What is the price of the resistance coil unit?
Prices are not published on the website. Add the resistance coil unit to the Enquiry Cart with the Add To Cart button on this page, or email [email protected] with the house code SCL-EAE-11262 and the quantity, to receive a quotation.
Does Lab Exports manufacture the resistance coil unit?
Yes. Lab Exports manufactures the resistance coil unit at its works at 11/315, Lalita Park, Laxmi Nagar, Delhi 110092, under house code SCL-EAE-11262.
