What is rheostat ??
,,,,???
Answers
Answer:
plz mark
Explanation:
an electrical instrument used to control a current by varying the resistance.
Answer:
Rheostat, adjustable resistor used in applications that require the adjustment of current or the varying of resistance in an electric circuit. The rheostat can adjust generator characteristics, dim lights, and start or control the speed of motors.
Explanation:
A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. ... Therefore they are mostly constructed as wire wound resistors. Resistive wire is wound around an insulating ceramic core and the wiper slides over the windings.
A rheostat or a variable resistor is a device or a component which allows changing of resistance in a circuit keeping the voltage same. In a conductor, electrons are attracted by the atoms.
- As nouns the difference between resistor and rheostat
- is that resistor is one who resists, especially a person who fights against an occupying army while rheostat is an electrical resistor, with two terminals, whose resistance is continuously variable by moving a knob or slider.
