RHEOSTAT BLACK WIRE

A Rheostat (Black Wire) is a variable resistor used to control the flow of electric current in a circuit by adjusting resistance. It is commonly used in physics and electronics laboratories for experiments involving current variation, voltage control, and circuit analysis.

This rheostat is constructed with high-quality black resistance wire wound over an insulated core, ensuring smooth and precise adjustment. It features a sliding contact (jockey) that allows easy variation of resistance, providing accurate and reliable performance.

Designed for durability and efficient heat dissipation, the rheostat is ideal for continuous use in educational and laboratory environments. It is an essential instrument for studying Ohm’s Law, electrical circuits, and resistance behavior.
