What is the speciality of rheostat?
Rheostat is an adjustable or variable resistor. It is used to control the electrical resistance of a circuit without interrupting the flow of current.Rheostats are used in applications that require high voltage and current.As a result of the reduction of size and power consumption in many of today’s electrical devices rheostats, once are very common item in commercial and industrial products, have been replaced by potentiometers. However there are still many applications that require a device that can be used to handle significant power and for these applications a rheostat is a very good choice. The most common uses today for rheostats are as light dimmers and motor speed controls. They are often used in arc lamps, pumps, fans and blowers, respirators, dental and medical equipment and model trains.
