Simple Introduction of Resistors

Everyone knows that resistor is an electronic component that can be found in many electronic devices. Such as phone, television, DVDs, computers and so on. We can say that almost every industrial can't lack of electronic components, especially for resistors.

Resistors were designed to cause a voltage drop by resisting the flow of electricity to a given point. They are commonly found in various electrical circuits or as components within electrical networks. The resistor can be characterized by three parameters including resistance (measured in ohms), heat dissipation (measured in watts) and its manufacturing tolerance.

Resistors have many types such as carbon film, carbon composition, metal film, wire-wound, grid resistors and so on. The common use resistors are the carbon film, carbon composition, metal film and wire-wound resistors. Carbon film resistor which is created by a narrow, spiral cut within the film is placed on an insulated substrate. The carbon composition resistor features a solid element made of ground carbon and ceramic. The metal film resistor is typically coated with nickel chromium and are used primarily in surface mounted applications. And the wire-wound resistor is made by wrapping wire around a ceramic core.

Electronic components is very useful in the industrail and they used in many products, such as phone, computer, television, radio, DVDs and so on. Thus it uses electronic components, you might use of resistors. Thescope of their using is very wide.

Here introduce the types and functions of resistors. To know more information of resistors, you can visit the electronic components websites.
