Yes.
A rheostat.
These devices could, in theory, be interchangeable. Variac is a (typically single coiled) variable transformer, whereas rheostat is a variable resistor. Although they may look just the same, they differ in one aspect - wire resistance. It should be as low as possible for variac, but it can differ on rheostats. So-you can use wire rheostat as a low efficiency variac and you can use wire variac as ridiculously huge rheostat, resistive range of which serves no practical purpose.

how to test a rheostat?
It is lost in heating the resistive material of the rheostat.
How do you install a rheostat in 1999 626 Mazda?
How do you take a rheostat out of a 2003 monte carlo
In a bridge circuit the unknown resistor is compared to the rheostat. When the meter across the bridge reads in the middle the unknown and the rheostat are the same value.
_____________ J| -_____/\/\/\/\_________+ | | | - + | |___i|i|___| E Well this is the circuit diagram , where r is the sliding jockey of the rheostat and a cell (E) is connected in parallel with the rheostat. By adjusting the jockey resistance of the rheostat can be altered which in turn would regulate the potential offered by the cell E to the main circuit. And thus a rheostat can be used as a potential divider.

Rheo
That is the dash light dimmer control switch.. Rheostat = Dimmer. Bright to dim.
