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.
