Changing the resistance value with a Sliding Contact Rheostat
A rheostat is similar to a potentiometer as they both control the input voltage by varying the level of resistance. Available in different resistance values.

EXAMPLE OF USE: Variable resistance
Suitable for use in many electricity experiments
Each rheostat is fitted with three terminals that allow it to be used as a fixed or a variable resistance or a potentiometer.
Connecting the two black plugs to the circuit, the rheostat works as a fixed resistance. Connecting the black and red plugs to the circuit, the rheostat works as a variable resistance.
With a more complex circuit schema is possible to realise a potentiometer.
