Sliding Rheostat Dual Tube
Product Code : SCL-PLE-11799
Quick Answer: The Sliding Rheostat Dual Tube carries constantan (Eureka) resistance wire on two vitrified ceramic tubes that can be linked in series or parallel, giving more power handling and a wider adjustment range than a single-tube rheostat.

How It Is Used
Connected through two terminals, the school lab rheostat acts as a variable resistor that controls the current in a circuit; using all three terminals turns it into a potential divider giving an adjustable voltage. Linking the two tubes in series gives more resistance, and in parallel more current capacity, for electromagnetism and power experiments that draw larger currents.
Frequently Asked Questions
Why choose the Sliding Rheostat Dual Tube over a single-tube rheostat?
Its two resistive tubes give higher power dissipation and a wider range of adjustment, and can be linked in series or parallel to suit the circuit.
