What Is The Function Of Variable Resistor

German physicist sir gs. It consists of a bare fixed resistance conductor with a terminal at each end plus a conductive wiper arm that moves along the fixed resistor to provide different resistance values.

Even more components are added to this type of a variable resistor so as to make them compatible with complicated electronic circuits.

What is the function of variable resistor. A variable resistor is in essence an electro mechanical transducer and normally works by sliding a contact wiper over a resistive element. When the ends of the resistor track connect with inputs of circuits. A high voltage variable resistor such as a focus pack is an example.

Ohms was able to discover a definite relationship between voltage current and resistance. There are switch mechanism variable resistors with an annular cross section which are used for the control of equipments. The function of variable resistor is to provide variable resistances in circuitary its also do the function of providing different values of current to different components.

The electrical resistance is varied by sliding a wiper contact along a resistance track. It would cover your need for 5000 or for values higher or lower. They are used as rheostats.

Another type of variable resistor is called a potentiometer or a pot. Besides its usefulness for designing it can be used to vary the resistance for purposes like a volume control or a brightness control. Pots are used as voltage dividers.

Definition of variable resistor. The function of variable resistor is to provide variable resistances in circuitary its also do the function of providing different values of current to different components. This means that they help connect circuits while leaving the resistance track open.

That is the function of a variable resistor providing a continuous selection of resistance values between its limits. A variable resistor is a resistor of which the electric resistance value can be adjusted. It is an electronic component.

It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit. Two common types of special resistors include light dependent resistors which change resistance as light levels change. A variable resistor although used in different industries is used in a relatively similar way.

Basically the function of a resistor is always to oppose the flow of current through it and the strength of this opposition is termed as its resistance. A variable resistor is called a potentiometer or pot for short. Pots are usually small and work by having their resistance control adjusted once and fixed often with a screwdriver.

Transistor Bc548 As A Switch

The example external circuit contains a dc motor. Bc548 as switch when a transistor is used as a switch it is operated in the saturation and cut off region as explained above. How To Use A Transistor As A Switch In Different Applications Elex Idea Blog Transistor Bc548 Transistor Switching Circuits Mosfet Transistor As A Switch Resistor r1 is a current limiting resistor which protects the transistor bc548 from over current. Transistor bc548 as a switch . A transistor switch which is used for opening or closing of a circuit that means the transistor is commonly used as a switch in the electronic devices only for the low voltage applications because of its low power consumptiontransistor work as a switch when it is in cutoff and saturation regions. The transistor behaves as a switch to ground because when the transistor is conducting it provides a ground path ...

Voltage Divider For Capacitors

When capacitors are connected in series and a voltage is applied across this connection the voltages across each capacitor are generally not equal but depend on the capacitance values. Note that the ratios of the voltage drops across the two capacitors connected in a series capacitive voltage divider circuit will always remain the same regardless of the supply frequency. Can I Use A Capacitive Divider To Run An Ac Dc Converter How Amps Work Voltage Divider Wikipedia For direct current and relatively low frequencies a voltage divider may be sufficiently accurate if made only of resistors. Voltage divider for capacitors . This is shown below. Voltage divider capacitor rc circuits. A voltage divider is a device which divides the applied voltage into two or more voltage outputs at a given ratio. Its one of the most useful and important circuit ele...
