Resistance Coil
Product Code : SCL-EAE-11260
Quick answer: The Resistance Coil is a circuit component that introduces a specified resistance into a physics experiment. Connected with a low-voltage supply, ammeter and voltmeter, it is used to verify Ohm's law, compare voltage drops and build series or parallel combinations with matching coils. The resistance value is agreed when ordering. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
A resistance coil is a length of resistance wire wound so that a known resistance takes little bench space. In a circuit it limits the current according to Ohm's law, I = V/R, and a voltmeter across it shows the potential difference it takes from the supply.
- Check the marked resistance value and rating before connecting.
- Connect the coil in series with a low-voltage supply, a key and an ammeter.
- Connect a voltmeter directly across the coil terminals.
- Vary the supply or a rheostat and record pairs of V and I readings.
- Plot V against I; the gradient gives the resistance of the coil.
With two or more coils, students can check that series resistances add, R = R1 + R2, and that parallel resistances combine as 1/R = 1/R1 + 1/R2.
