Key features and benefits - Robust construction for lab use The sliding rheostat uses oxidised and insulated wire tightly wrapped around a porcelain tube and mounted on a metal bracket, delivering a durable and stable component for demonstrations and experiments. - Clear, adjustable control The sliding rheostat acts as a control circuit by changing its own resistance, allowing precise adjustment of current and voltage in a circuit. - Versatile regulator for lab and equipment This electric sliding rheostat can serve as a current and voltage regulator for research and demonstration in the laboratory, and it is suitable for excitation and speed control in power generation systems and DC motors. What makes it work - Function By adjusting the resistance through the sliding mechanism, it regulates the flow of current and the voltage across the circuit. - Materials and construction Oxidised insulated wire is tightly wrapped around a porcelain tube and attached to a metal bracket, providing a compact and reliable design. - Compatibility and applications Ideal for laboratory experiments, educational demonstrations, small power generation setups, and DC motor control, where variable resistance is needed to regulate performance. Use scenarios - Educational lab demonstration Use the rheostat to illustrate how changing resistance affects current and voltage in a circuit, supporting hands-on learning of Ohm’s law and circuit behavior. - Excitation and speed control in DC systems Employ the rheostat to regulate excitation current or the speed of DC motors in power generation test rigs or equipment demonstrations. - Research and development bench testing Integrate the rheostat in lab rigs to adjust current and voltage during tests of electronic circuits, power supplies, or control experiments requiring variable resistance.
