Copper would not be practical because of its high conductivity. The result of using copper would be that you would need to make very big rheostats to get any useful resistance.

How do you fix the dash lights in a 1995 subaru impreza There are no fuses blown and the gauges all work?
Bulbs burned out? Dimming rheostat is open? Bad headlight switch? Make sure parking and tailights are working (same circuit)
What determines which one of the terminal of a rheostat in positive when connected in a series?
Electron flow is from negative(-) to positive(+), the rheostat would have to be on the negative side for the device being controled, before the device, e.g. light bulb.AnswerIt doesn't matter. Rheostats don't have positive or negative terminals.
What does the inside of a rheostat switch look like?
A rheostat is a mechanically operated variable resistor, consisting of a wire coiled around a rod (or ring) the contact slides over the coil, varying the length of wire that the current passes through, giving an adjustable voltage drop.
What is the difference between a potentiometer and a rheostat?
The fundamental difference between a potentiometer (pot) and a rheostat is that the former is a three terminal device, while the latter is a two terminal one. Let's look at both. When we consider either device, we are looking at a resistive element with a "wiper" or "adjustable contact" to which we can attach a wire. The only difference between the two devices is that the resistive element can have an electrical contact (terminal) at both ends or at just one end. The pot has terminals at each end of the resistive element, and the rheostat has a terminal at only one end. Lastly, a pot can be used in place of a rheostat, but not the other way around.

Why are rivers so important in new zealand?
Because it helps provide us with clean air, and it protects our native wildlife (eg our birds etc)

What is the purpose of a rheostat in the determination of an unknown resistor?
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.
How a rheostat is used is as a potential divider?
_____________ 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.
