Adjustable Power Resistor

What is an Adjustable Power Resistor?

An adjustable resistor is an inactive two-terminal electrical device that undergoes electrical resistance as a circuit element. In electronic circuits, resistors are installed to mitigate voltage flow, automate signal levels, distribute voltages, resist active components, and eliminate transmission lines, among other applications. High-power resistors that can generate several watts of heat instead of electrical energy can be utilized as test loads for generators, power distribution systems, and motor controllers.

What is the function of an adjustable resistor?

Variable resistors are widely employed in an electric circuit to monitor the power of the current, as variable resistors allow the resistance to be adjusted to a certain value. With variable resistors, you may change the resistance while maintaining a constant current to change the voltage value.

How are adjustable resistors made?

Construction. A wiper that travels along the resistance track as the spindle is turned and a resistance track with connections at both ends make up a variable resistor. Carbon, cermet (a ceramic and metal combination), or a coil of wire may be used to make the track (for low resistance).

Functions of adjustable power

Resistors are widely used in electronic equipment and are typically components of electrical networks and electronic circuits. Practical resistors can be made of a variety of materials and shapes as discrete components. Additionally, integrated circuits incorporate resistors. The resistance of a resistor determines its electrical purpose. Typical commercial resistors are produced across a range of more than nine orders of magnitude.

The nominal value of the resistance is within the component's stated manufacturing tolerance. The sliding resistance tap can be attached to a knob that an operator can reach when continuous modification of the resistance value during equipment operation is necessary. A rheostat is a device with two terminals that performs this function.
