Resistor Types Of Resistors Fixed Variable Linear

For most standard circuits you dont need to worry about the types of resistors you choose.

Resistor types. Different resistor materials are used for fixed resistors. Another type of resistor called a wirewound resistor is made by winding a thin metal alloy wire nichrome or similar wire onto an insulating ceramic former in the form of a spiral helix similar to the film resistor above. The fixed resistor type is the most common resistor when people talk about a resistor they most probably mean a fixed resistor.

The wattage rating indicates the amount of power the resistor can safely dissipate as heat. Resistors can be seen in almost all electronic circuits. Which resistor type to choose for which application is beyond the scope of this article.

Types of resistors the two main characteristics of a resistor are its resistance r in ohms and its power rating p in watts. There are many types of resistors and they can be divided into two groups namely fixed resistor and adjustable resistor variable resistor. Photo resistor or photo conductive cell or ldr.

If you are building any of these types of circuits see if the schematics specify the resistor type. These types of resistor have high stability and can also withstand high powers but are usually bulkier compared to other types of resistors. The resistor is coated with an insulating material to protect the conducting material from the surrounding environment and vice versa.

Resistor types for a piece of conducting material to be made into a practical resistor a pair of electrodes and leads are attached so that current can flow. A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. Their values are determined during the design phase of the circuit.

They are used in electronics circuits to set the right conditions in a circuit. In other words thermisters is a type of variable resistor which notices the change in temperature. Thermisters is a two terminal device which is very sensitive to temperature.

The main function of the resistor is to resist the flow of electric current and regulate the flow of electrons. In electronic circuits resistors are used to reduce current flow adjust signal levels to divide voltages bias active elements and terminate transmission lines among other uses. The resistance r provides the required reduction in current or the desired drop in voltage.

Wirewound types of resistor. These types of resistor are made by firing certain metals blended with ceramics on a ceramic substrate. The picture to the right shows an axial carbon film resistor the most common type.

These different resistor types are used for different applications. Fixed resistors are by far the most widely used type of resistor. Fixed resistors have a constant resistance value.
