Variable Resistor What Is It Used For

Some types of resistors are variable letting you set their resistance by sliding a slider or turning a knob. 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.

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.

Variable resistor what is it used for. The two most common used variable resistors are rheostat and potentiometer. They are used as rheostats. A variable resistor is used because a potential divider with 3 terminals is known as a potentiometer.

The position of the wiper determines the output voltage. Varying resistance changes the amount of current flowing in a circuit. Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment.

It allows the user to dial in any resistance form 0 ohms to the maximum rated resistance of the pot. A variable resistor although used in different industries is used in a relatively similar way. The resistor is the most common electronic component and is used to limit andor control the voltage and current in an electronic circuit.

Variable resistance is also known as a potentiometer or a pot. Resistors are carefully manufactured to provide a predetermined value of electrical resistance which may range from 01 ohms to 100000000 ohms. A potentiometer is a manually adjustable variable resistor with three terminals.

A variable resistor is an electro mechanical transducer that generally works by sliding a contact wiper over a resistive element. In this case all three terminals are in use. A variable resistor is a resistor in which the electric resistance value is adjustable.

When the ends of the resistor track connect with inputs of circuits a variable resistor is used as a potentiometer. What is variable resistance. It is commonly used to change the value of current across a circuit to find relationships of current and voltage.

Variable resistors can be used to adjust circuit elements such as a volume control or a lamp dimmer or as sensing devices for heat light humidity force or chemical activity. Two terminals are connected to a resistive element the third terminal is connected to an adjustable wiper. This means that they help connect circuits while leaving the resistance track open.

A resistor whose resistance value can be adjusted as per requirement is called as variable resistor. It is basically an electro mechanical transducer which varies resistance by sliding contacts wiperslider over a resistive element. A variable resistor is used in cicuits to vary the magnitude of resistance passing through the resistor.
