WebA rheostat is tested by measuring the resistance between any two fixed and variable points. The change in the resistance and the movement of the wiper from maximum to minimum should be proportional to each other. The value thus obtained should be similar to … WebSep 8, 2024 · A rheostat is based on Ohm’s law, which is given by: R = V/I where R= resistance V= voltage I= current From the above law, we can see that resistance is inversely proportional to current. This means that an increase in resistance decreases the current and vice-versa. Also, according to the following formula: R = ρL/A where R = resistance

WebA rheostat is a type of variable resistor used to control the flow of electric current. It is a device that varies the magnitude of an electromotive force (EMF) applied to a circuit, in response to the voltage or power supplied to that circuit. The term rheostat derives from the Greek word “rheos,” meaning flow. How do Rheostats Work?
