A variable resistor is used in cicuits to vary the current passing through the resistor. A variable resistor although used in different industries is used in a relatively similar way.

The Circuit Shown Is Used To Control The Brightness Of Two

The maximum resistance that a preset can provide is written on it.

Variable resistor used for. Varying resistance changes the amount of current flowing in a circuit. Some types of resistors are variable letting you set their resistance by sliding a slider or turning a knob. When the ends of the resistor track connect with inputs of circuits a variable resistor is used as a potentiometer.

Rheostats are much related to the potentiometers in terms of construction. User control of circuit functions. A variable resistor can also be used as a potentiometer when both ends of the resistance track are connected to the input circuit and one of the said ends of resistance track and wiper terminal is connected to the output circuit.

The potentiometer is the most common variable resistor. Rheostats are very similar in construction to potentiometers. In this case all three terminals are in use.

You can for example use a variable resistor to control the loudness of an amplifier the pitch of a musical tone or the speed of a motor. They can also be used to control the voltage across devices in a circuit too. Presets are just like.

A potentiometer is an ordinary variable resistor. They are used as rheostats. A digital variable resistor is a type of variable resistor.

There are 3 pinsterminals on a preset. Therefore in applications where current control or voltage control is needed these type of resistors come handy. How to use a preset.

A movable metal is rotated in clockwise or anticlockwise direction that changes the resistance of preset. This means that they help connect circuits while leaving the resistance track open. Types of variable resistors.

A digital variable resistor is a type of variable resistor where the change. As the resistance increases in the variable resistor the current through the circuit decreases and vice versa. If 100k is written on preset it means that we can vary its resistance from 0 ohm to 100k.

It is commonly used to change the value of current across a circuit or to act as a voltage divider. Types of variable resistors potentiometer.
