Resistance Box 1000 Ohms Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11277
The apparatus provides selectable resistance up to the stated 1000-ohm capacity. Its resistance sections are arranged for convenient circuit selection, allowing students to change the inserted resistance without replacing individual loose resistors during each observation.
The laboratory format supports repeated demonstrations and structured student practicals. The enclosed design keeps the internal resistance elements organised, while the top-mounted selectors and connection terminals provide access to the experimental circuit. Exact increments, tolerance, current rating and internal coil material require confirmation.
Key Features
1000-ohm capacity: Provides selectable resistance values within the stated maximum range.
Known-resistance selection: Allows a defined resistance to be inserted into a laboratory circuit.
Supports Ohm’s law practicals: Helps students observe how changing resistance affects current at a stated voltage.
Multiple resistance sections: Enables different values to be combined according to the selector arrangement.
Accessible connection terminals: Supports connection to suitable power sources, meters and circuit apparatus.
Enclosed laboratory format: Keeps resistance elements protected and organised during instructional use.
Suitable for repeated experiments: Designed for teacher demonstrations and supervised student laboratory sessions.

How to Use the Resistance Box 1000 Ohms
Place the resistance box on a stable, dry laboratory bench.
Keep the circuit power switched off while making connections.
Connect the box in the required circuit position using its terminals.
Select the required resistance according to the marked values.
Ask the instructor to verify the circuit and selected resistance.
Switch on the supply and record the required voltage or current readings.
Switch off the supply before changing the resistance selection.
Disconnect the apparatus after completing the experiment.
Safety note: Never change selectors while excessive current is flowing. Do not exceed the confirmed current or power rating, and avoid short-circuiting the resistance box or connected power source.
Care and Maintenance
Keep selectors, terminals and the top panel clean and dry.
Insert and remove selector plugs gently to prevent contact damage.
Inspect terminals and internal connections if readings become unstable.
Store the apparatus in a dry, dust-free cabinet after use.

Frequently Asked Questions
What is a Resistance Box 1000 Ohms used for?
It is used to insert a selected known resistance into an electrical circuit for measurement, comparison and instructional experiments.
Can this resistance box be used for Ohm’s law experiments?
Yes. It can provide known resistance values while students measure the corresponding voltage and current under supervised conditions.
How is the total resistance selected?
Resistance is selected through the unit’s marked selectors or plugs. The total inserted resistance is determined by the confirmed internal arrangement and selected values.
Does the box provide every value from 0 to 1000 ohms?
The maximum stated capacity is 1000 ohms, but the available increments have not been verified. Confirm the resistance sequence before ordering.
Can resistance be changed while the circuit is powered?
The recommended practice is to switch off or reduce the circuit current before changing the selection. This protects the contacts and connected apparatus.
Is the Resistance Box 1000 Ohms suitable for schools?
Yes. It is suitable for supervised secondary-school, college, polytechnic and vocational electrical laboratory experiments.
