Feature●1. Sliding leotat adopts oxidized insulating wire, tightly wrapped in porcelain tube and fixed to metal bracket●2. Slide leotat works as a control circuit by changing its own resistance value●3. Electric slide leotat can be used as a current and voltage regulator for laboratory research and demonstration in laboratory, excitation and speed control of generating equipment and DC motors●4. Experiment leotat is highly practical and often used in school physics classes in electrical experimentsDescription
