Rheostat 6 Inches
Product Code : SCL-EAE-11284
Quick answer: The Rheostat 6 Inches is a compact sliding rheostat with a nominal 6-inch format. Its movable contact sets how much resistance wire lies between the chosen terminals, so students can control current, watch meter readings change and carry out introductory Ohm's law work. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the 6-inch rheostat controls current
When the rheostat is placed in series with a lamp or resistor, the circuit resistance is the sum of the two: R total = R load + R rheostat. Sliding the contact changes the rheostat part of that sum, so for a fixed supply voltage the current I = V / R total goes down as more winding is brought in and up as less is used.
- Check the resistance and maximum current rating of the rheostat against the planned circuit.
- With the supply off, connect the correct terminals as shown in the experiment diagram.
- Move the slider to a high-resistance position.
- Switch on the low-voltage supply and move the slider gradually, reading the ammeter and voltmeter at each step.
Recording the readings in a table lets students see the inverse link between resistance and current, a first step before plotting a full V-I graph.

Frequently asked questions
Why start with the slider at high resistance?
Starting at high resistance keeps the first current small. The current is then raised gradually, which protects meters, lamps and the winding itself.
Is the 6-inch rheostat suitable for introductory physics?
Yes. It is intended for introductory current-control, resistance-current and supervised Ohm's law practicals in school and college laboratories.
