Wire Wound Resistors

Abstract

Resistor is a passive electronic component having resistivity and is used for various applications in any electronic equipment as a part of electronic circuit used in it. Resistors offer resistance to flow of current. Resistor can be broadly classified into fixed resistor and variable resistor. Again fixed resistor is grouped into carbon composition, metal composition, oxide coated and wire wound resistors. Resistors are characterised by resistance value, power rating (in watts) and tolerance. Wire wound resistors, which are used in electronic equipments and instruments where high precision and more power dissipation are specified.
