A rheostat is an electrical device that is used to vary voltage across a network to which it is connected. Since resistance is actually responsible for voltage drop, so by varying the resistance, it is possible to obtain different values of voltage.
Rheostats. A rheostat is an electrical component that has an adjustable resistance. It is a type of potentiometer that has two terminals instead of three. The two main types of rheostat are the rotary and slider.The symbol for a rheostat is a resistor symbol with an arrow diagonally across it.t is a type of potentiometer that has two terminals instead of three.
