A Study on Temperature Properties of Different Types of Fixed Resistor

Abstract:

This paper studies the relationship between the value of temperature variation and the resistance value of each type of general resistors as well as also determines the temperature coefficient value of each resistor type. All obtained results will be compared to build a guideline for selecting the resistor to apply in any applications accurately and properly. Each type of 1 k-ohm resistor that has different power is used to study its properties and is controlled its temperature variation to be in range of 20 to 30 degree Celsius. An experimental setup to control the temperature variation of the resistors in this paper is that the resistors are put into an oil bath controlled its temperature after that measuring the changed resistance value of the resistors following oil temperature in the bath. The experimental result demonstrates that the temperature variation affects to change the resistance value of Carbon Film type the most but affects to change the resistance value of Wire Wound type with low power the least.
