what is a variable resistor called The variable resistor also called a potentiometer or rheostat that is used in circuits for resistance change It is a passive component and comes with 3 pins through this component value of resistance can be varied according to changes in the position of the moving wiper existing on the resistor
What Is A Variable Resistor Variable resistors are versatile components used to create adjustable voltage dividers and sensors in a range of applications Common types include potentiometers Variable Resistor Arrays VRAs and Variable Resistor Networks VRNs A variable resistor is in essence an electro mechanical transducer and normally works by sliding a contact wiper over a resistive element When a variable resistor is used as a potential divider by using 3 terminals it is called a potentiometer

A variable resistor is the type of resistor which changes the flow of current in a controlled manner by offering a wide range of resistances As the resistance increases in the variable resistor the current through the circuit decreases and vice versa What is a Variable Resistor A variable resistor is a passive circuit element used in electrical and electronic circuits and devices to insert a resistance that can be changed as per requirements It is also known as a potentiometer It is simply a resistor which has an adjustable resistance
Variable resistors can be categorized into three types Potentiometers Rheostats Digital potentiometers Symbols for Variable Resistors A variable resistor is an electronic component that allows users to adjust the resistance within a circuit thereby controlling the flow of electric current It is often used for tuning calibration and adjustment purposes in electronic devices Types of Variable Resistors There are three main types of variable resistors each with its unique

This article will provide an overview of variable resistors their working principle types and applications What is a Variable Resistor A variable resistor also known as an adjustable resistor or a rheostat is a type of resistor whose resistance can be adjusted by moving a mechanical component such as a sliding contact or a V IR What is a Variable Resistor A variable resistor possesses an adjustable electrical resistance value making it a crucial component in electronic circuits for adjusting current or voltage according to Ohm s Law
Definition of a Variable Resistor As the name suggests the variable resistor is a passive three terminal device that can adjust its resistance via third terminal located between two terminals so that the obstruction to the flow of current goes up and down R is the resistance in ohms This equation tells us that the current flowing through a circuit is directly proportional to the voltage applied across it and inversely proportional to the resistance of the circuit Operational Principles Variable resistors are integral in circuits where there s a need to adjust the current or voltage
