Variable Resistors Hackatronic A varistor is a voltage dependent, non linear resistor whose resistance changes significantly with applied voltage. the term varistor is derived from “variable resistor”, but unlike potentiometers or rheostats, its resistance varies automatically with voltage, not mechanically. Learn electronics concepts, circuits, and practical projects with clear tutorials, diagrams, and real world applications for students, engineers, and hobbyists.
What Are Potentiometers Or Variable Resistors Resistors are fundamental electronic components that limit, regulate, or set the flow of electric current in a circuit. while they may appear simple, there are different types of resistors designed for specific purposes and operating environments. A rheostat is a variable resistor specifically designed to control current in an electrical or electronic circuit without interrupting the circuit. unlike potentiometers, which are mainly used for voltage division, rheostats are typically employed in series with a load to adjust current flow. A trimmer resistor, commonly known as a trim pot (trimming potentiometer), is a small adjustable resistor designed for fine tuning, calibration, and preset adjustment of electronic circuits.

Variable resistors are essential in controlling electronic circuits, allowing precise control of electrical resistance in circuits. in this article, we'll explore six different types of variable resistors, explaining how they each find their use in circuits. If you ever wanted to adjust a circuit using a digital version of a potentiometer (variable resistor) controlled by an arduino then this is the easy way to do it and at a price that won't break the bank either. Learn about various types of variable resistors such as potentiometer, trimpot, preset, digital potentiometer and rheostat. A variable resistor is defined as a resistor whose value of electrical resistance can be changed on demand. it is a common component in electronic circuits that allows the adjustment of current or voltage according to ohm’s law.
