Rheostats 10 Ohms- Continuous Constantine Type
Description
The Rheostat 10 Ohms - Continuous Constantine Type is a variable resistor used primarily for controlling current in electrical circuits by continuously varying the resistance.
Key description points include:
It uses a resistive wire made of Constantan (a copper-nickel alloy) known for a low temperature coefficient of resistance, ensuring stable performance.
The device is designed for continuous adjustment, where a sliding contact moves over a wire coil to alter the effective resistance.
It typically consists of three terminals: two fixed terminals connected to the wire resistive element and one sliding terminal (wiper) that adjusts the resistance by changing the length of wire in the circuit.
The resistance can be smoothly adjusted from zero up to the rated 10 Ohms, making it ideal for experiments requiring gradual variation of current.
Construction usually includes a cylindrical insulating body on which the resistance wire is wound, with the sliding contact pressing against it.
Commonly used in laboratory settings for research, demonstrations, and teaching electrical principles.
