Web26 de set. de 2024 · How Does a Rheostat Work? The basic principle of a rheostat is Ohm's law. Ohm's law states that "current is inversely proportional to resistance for a given voltage." That pretty much means that the current will decrease as the resistance increases. It also means that it may increase as the resistance decreases. WebA rheostat is a Resistance element with considerable length. It is usually metallic in nature. The defining equation is R= pl/A Where; p=resistivity of the element (it is supposed to be ro; but I don't know how to type that in) l=length of the wire. A= area of cross section of the wire.
