content: For engineers in the electronics industry, electronic components are the basic element. There are several types of components, in this artical,I would like to share some basic knowledge about resistors.Resistor is the most frequently used in all electronic circuits. Resistor is called a resistive material because it has a hindrance to the current. It can cause changes in electron flux. The smaller the resistor, the greater the flux of electrons and vice versa.Most of the time, the resistors we used are with fixed values. For example,Wire Wound Resistor can be made as a precision resistor with a tolerance of 0.005% and a very low temperature coefficient.The disadvantage is that the parasitic inductance of the wire wound resistor is relatively large and cannot be used for high frequencies. The volume of the wire wound resistor can be made very large, and then an external heat sink can be used as a high power resistor.Carbon Composition Resistor is simple in process and easy to obtain raw materials, so the price is the cheapest. However, the performance of the carbon composite resistor is not so good, the tolerance is relatively large (that is, the precision resistor cannot be made), the temperature characteristics are not good, and the noise is usually large.Carbon Film Resistor mainly forms a carbon mixture film on the ceramic rod, for example, directly coating a layer, the thickness of the carbon film and the carbon concentration thereof can control the size of the resistor.I would appreciate it if you can complement more types.

content: What does the original poster mean by electron flux? The term is normally used to describe the strength of an electric field. It makes no sense in the context of the original post.https://en.wikipedia.org/wiki/Electric_flux

content: This exact post was posted word for word in almost all the electronics related forums across the web. It's some form of spam but I'm not quite sure how it works. Possibly some keyword manipulation?
