Frequently Asked Questions
Q: What resistance values does this sliding rheostat come in?
A: This sliding rheostat is available in three resistance configurations: 10Ω, 20Ω, and 50Ω. All variants are rated at 1.5A, making them suitable for a wide range of standard physics and electronics experiments.
Q: Can this rheostat be used as both a fixed and variable resistor?
A: Yes! This sliding rheostat is designed for dual-mode use. By adjusting the slider position, it functions as a variable resistor. When the slider is set to a fixed point and used via appropriate terminals, it can also serve as a fixed resistor — offering great versatility for different experiment setups.
Q: Is this rheostat suitable for classroom use?
A: Absolutely. The sliding rheostat is specifically designed with students and educators in mind. Its compact size (15 cm × 4 cm × 5.5 cm), metal construction, and clear sliding mechanism make it an excellent hands-on learning tool for middle school and high school physics labs.
