The difference between carbon composition resistor and wire wound resistor
|Carbon composition resistor
||Wire wound resistor
|Its power rating is from ¼ W to 2W.
||Its power rating is from 1W to 200W.
|It can be used at high frequencies.
||It cannot be used at high frequencies.
|It has high tolerance and hence, accurate value of resistance cannot be obtained.
||It has low tolerance and hence, accurate value of resistance can be obtained.
|It has low stability and reliability.
||It has higher order of stability and reliability.
|It is suitable for high frequency circuits.
||It is not suitable for high frequency circuits.
|It is small in size and light in weight.
||It has big size which is not suitable for many of the applications.
|It has low temperature coefficient value.
||It has high temperature coefficient value.
