What is Resistor?


Definition – What does Resistor mean?

A resistor is a most important electrical component that limits the flow of current. One or more components can be used to provide the correct amount of electric current to the specific components within a device. Resistors are soldered onto the printed circuit board in order to limit the amount of current that flows to different electrical paths. If too slight current reaches a component, it may not operate, and if too much current is enabled though, it can damage the device. Therefore, resistors play a significant role in an electronic circuit.

Glossary Web explains Resistor

There are multiple types of resistors exist, but the most of the resistors are made up of carbon and an insulating material called ceramic in which the current flows in one end and the residual current flows out the other. The resulting output is inversely proportional to the resistance. This is definite in Ohm’s law that states that the current is equal to the voltage divided by the resistance.

Almost all the resistors are often color-coded in order to visually represent their resistance levels. Typical an axial-lead resistor is cylindrical in shape and has certain colored stripes. The first few stripes represent digits that are followed by a stripe which represents a multiplier. On the other end is a stripe represents the tolerance that describes the accuracy of the resistor. Some resistors also contain one or more band that represents the temperature coefficient.
