How many types of Resistors
The Different Types of Resistor Resistors, ( R ) are the most fundamental and commonly used of all the electronic components, to the point where they are almost taken for granted. There are many different Types of Resistor available for the electronics constructor to choose from, from very small surface mount chip resistors up to large wirewound power resistors. The principal job of a resistor within an electrical or electronic circuit is to “resist” (hence the name Resistor ), regulate or to set the flow of electrons (current) through them by using the type of conductive material from which they are composed. Resi stors can also be connected together in various series and parallel combinations to form resistor networks which can act as voltage droppers, voltage dividers or current limiters within a circuit. A Typical Resistor Resistors are “ Passive Devices “, that is they contain no source of power or amplification but only attenuate or reduce the voltage or c...
