Wheatstone Bridge Laboratory Kit

Product Code : SCL-EAE-11163

The Wheatstone Bridge Laboratory Kit is a physics laboratory apparatus used for resistance comparison, null-point detection, and unknown resistance measurement by the Wheatstone bridge method. It is suitable for school physics labs, colleges, electrical practical classes, STEM laboratories, distributors, and institutional procurement buyers.

Product Description

The Wheatstone Bridge Laboratory Kit from Lab Equipments Ambala is best aligned with the verified Meter Bridge or Wheatstone Bridge With Pencil Jockey, listed under Physics Lab / Electrical and Electronics. The closest verified product code is EL-EAE-10289.

This apparatus helps students perform standard bridge experiments using a resistance wire, jockey contact, galvanometer, resistance box, key, and low-voltage source. The closest verified Lab Equipments Ambala information states that the related meter bridge uses 24 SWG constantan wire on a wooden meter scale for resistance and bridge experiments.

Key Features

• Wheatstone bridge method: supports comparison of known and unknown resistances.
• Null-point experiment: helps students locate balance condition using a galvanometer.
• Verified related product code: closest confirmed listing is EL-EAE-10289.
• 24 SWG constantan wire: verified for the related Lab Equipments Ambala meter bridge listing.
• Wooden meter scale: provides a visible length reference for balance-length measurement.
• Pencil jockey contact: supports smooth point-contact testing along the bridge wire.
• Capacity not applicable: this is an electrical measurement apparatus, not a volume or mass container.

How to Use the Wheatstone Bridge Laboratory Kit

1. Place the bridge apparatus on a clean, dry, stable laboratory bench.
2. Connect the known resistance, unknown resistance, galvanometer, key, and low-voltage DC supply according to the practical circuit diagram.
3. Check all terminals and leads before switching on the circuit.
4. Touch the pencil jockey lightly on the resistance wire and move it along the scale.
5. Find the position where the galvanometer shows zero or minimum deflection.
6. Record the balance length from the wooden meter scale.
7. Calculate the unknown resistance using the Wheatstone bridge balance relation provided in the laboratory manual.
8. Switch off the supply before changing resistance values or circuit connections.

Safety note: Use the Wheatstone Bridge Laboratory Kit only with a suitable low-voltage DC source under instructor supervision. Do not connect the apparatus to mains electricity, do not press the jockey forcefully on the wire, and do not leave current flowing longer than required.

Care & Maintenance

• Keep the resistance wire clean, straight, and free from kinks or corrosion.
• Store the bridge apparatus in a dry cabinet after each experiment.
• Use the pencil jockey gently to avoid damaging the wire and scale surface.
• Inspect terminals, screws, leads, and wire continuity before practical sessions.

Frequently Asked Questions

What is a Wheatstone Bridge Laboratory Kit used for?

A Wheatstone Bridge Laboratory Kit is used to compare resistances and determine an unknown resistance by finding the bridge balance point.

What is the closest verified Lab Equipments Ambala product?

The closest verified product is Meter Bridge or Wheatstone Bridge With Pencil Jockey, Product Code EL-EAE-10289.

What wire is used in the verified related meter bridge?

The verified related listing states that the meter bridge uses 24 SWG constantan wire on a wooden meter scale.

What instruments are usually required for the experiment?

A typical Wheatstone bridge experiment uses a galvanometer, resistance box, plug key, connecting leads, unknown resistance, and a low-voltage DC source. Confirm whether these are included or supplied separately.

Why is a galvanometer used in a Wheatstone bridge?

A galvanometer detects the null point. At balance, the galvanometer shows zero or minimum deflection, allowing the unknown resistance to be calculated.

Can the kit be connected to mains electricity?

No. The kit should be used only with a suitable low-voltage DC source under instructor supervision and must never be connected directly to mains electricity.
