Rheostat 12 Inches – Adjustable Resistance Laboratory Instrument

The Rheostat 12 Inches is a variable resistor used to adjust the resistance in an electrical circuit and control the current flowing through it. Manufactured by Elmo Agencies, a trusted scientific manufacturer in Ambala, it is suitable for physics laboratory experiments, electrical demonstrations, and educational applications.

A rheostat is a type of variable resistor designed to change the effective resistance of a circuit. By adjusting the sliding contact, the resistance can be varied, allowing the current in the circuit to be controlled. The 12-inch design provides a practical format for laboratory demonstrations and experiments involving resistance and current.

Key Features of Rheostat 12 Inches

• 12-inch rheostat design
• Adjustable resistance using a sliding contact
• Suitable for current-control experiments
• Designed for laboratory and educational use
• Useful for demonstrating the relationship between resistance and current
• Practical instrument for electrical experiments

Applications

• Physics laboratory experiments
• Resistance and current demonstrations
• Electrical circuit experiments
• Educational practicals
• Technical training
• Electrical and electronics applications

Working Principle

When the sliding contact is moved along the resistive element, the effective length of the resistance wire in the circuit changes. This changes the circuit resistance and, consequently, affects the current flowing through the circuit when the supply conditions remain the same.

Conclusion

The Rheostat 12 Inches by Elmo Agencies is a practical variable-resistance instrument for controlling current in electrical circuits. Its adjustable design makes it suitable for physics laboratories, educational demonstrations, electrical experiments, and technical training.
