A resistor is determining the flow of current in an electrical circuit. Whenever there is a high circuit resistance, there is a small current flow. When there is a low resistance, there is a large current flow. The voltage, current and resistance were connected to electrical circuits. This takes place through the Ohm’s Law.
The resistors are used for regulation of current and these resist the current flow with the extent of performing with the use of ohms measurement. It can also be found in most electronic circuits available and it is also very small to obtain numbers printed on it.
There are several resistor types used in an electronic circuit. Each one has different property which is usually dependent upon its construction as well as manufacturer. For this reason, they got various resistors that have been designed for a certain application. For the past years, resistor types have been utilized in the mass production of electronics but these are now undergoing changes.
Fixed and Variable Resistors
They have been the main categories of resistors. They fit into two different types of fixed and variable resistors. Fixed resistors are one of them and this has been regarded as a common kind of resistors. These have been utilized in an electronic circuit for setting the proper conditions in the circuits. The values of a fixed resistor can be determine on the design phase of the circuit. However, they must never be transformed for circuit adjustment.
The variable resistors have been the resistor types that re composed of slides and elements of fixed resistors where the main resistor elements tap into. They are providing 3 connections to a component in which two of them are integrated to a fixed element and one distinguishes the slider.
The other resistor type category has been the fixed resistor type which has numerous types available. Carbon composition is one and this is actually a very well known type. But the truth is that this has been seldom used. Carbon film is another type. This is usually formed as the hydrocarbon on a ceramic former is cracked. There is also a metal oxide/metal film which is now widely used resistor form as the metal film is being deposited into the ceramic rod.
The other type of resistor is the wire wound and thin film which has specific uses. The last resistor category is leaded and non leaded resistors which have surface mount and leaded resistors.
