What is a rheostat? A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. The construction is very similar to the construction of a potentiometers. It uses only two connections, even when 3 terminals (as in a potentiometer) are present.
A rheostat is a resistor with variable resistance.There are many type of rheostat,involved of a rotary-type rheostat and a sliding rheostst.I dunn know much about the rotary-t â¦ ype rheostat but I can tell u how does a sliding rheostat work. The purpose of the rheostat is use to change the resistance of the circuit. The rheostat is use to define Ohm Laws th â¦ e 2nd situation is use to find out what the fixed resistor's resistance. 3rd purpose: used to control the resistance of circuit. eg Radio.
