WebSep 8, 2024 · Rheostat is generally used in applications where high voltage or current is required such as: Changing the light intensity of a light bulb. An increase in the resistance of the rheostat decreases the flow of electric current, leading to dimming of lights and vice-versa. Generators Motor speed Heater and oven temperature control Volume control WebWhat is rheostat? The electric current flowing through an electrical circuit is determined by two factors: the amount of voltage applied and the total resistance of the electrical circuit. If we reduce the circuit resistance, the …

Web\$\begingroup\$ Sometimes rheostats are used to set the gain of a system; a circuit may be designed so the highest resistance setting will produce e.g. a gain of ten, but an open circuit might produce a gain of 1,000. In such cases, having the contact momentarily open to expose the full resistance of the element would produce an excessive level of gain, but … WebThe unique high voltage resistor must be "paired" with a low value resistor to insure ratio tracking under changes of temperature, voltage, humidity and time. In addition, the high value of resistance in the feedback network means a susceptibility to very low current interference. It can be seen that currents as low as 1 X 10-9 amps will result ...
