what is a variable resistor example For example if a variable resistor has 100 between ends x and y The total length of the element is 10 m If the wiper is placed at a position on the element where the distance between the point y and the wiper is 4 m Then calculate the effective resistance Here R 1 100 l 10 m l1 4 m

Variable resistance is a type of electrical component that allows for the adjustment of its resistance value This property makes variable resistors a versatile tool in a wide variety of applications It is a commonly used resistor in circuits where it controls the current flow in the circuitry 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 They can also be used to control the voltage across devices in a circuit too

Variable resistors are resistors that change resistance from zero to a certain maximum value They are commonly used as volume controls and voltage regulators Variable resistors can be categorized into three types Potentiometers Rheostats Digital potentiometers Symbols for Variable Resistors Potentiometer Types of Variable Resistors Variable Resistors are resistors whose resistance values can vary according to some factor applied to them For example potentiometers are variable resistors that changes when a user adjusts the knob Photoresistors are variable resistors which change according to the light that strikes its surface

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 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
