CARBON RESISTOR (High Stability carbon Resistor).
(OP)
Dear ALL,
Please can you tell me which one of the Resistor are more stable (to be used as a shunt), Carbon Film Fixed Resistor or Carbon Composition Resistor for measuring the potential across the resistor, in order to calculate the current passing through (for sacrificial anode cathodic Protection System application). The current would be in the range of 0.1milliamps to maximum of 100milliamps. The resistor would be in Operation continously over years. The operating Temperature would be -45deg.C to +45 deg.C.
Your help and early reply would be very much appreciated.
Kind Regards

BTW, there is a component forum which might be a better place for future questions like this.

I do not know about the metal film, metal oxide, and also does not to be very accurate.
where can contact / I find the BTW (I not Familiar with the term)?

Go here and search for composite resistors.

A lot of designs went haywire when purchasers couldn't find comps and switched in carbon/metal films instead.

FYS, have you considered using a 4-lead "Kelvin" type resistor like those at:
