WebbThe most common material used to make a resistor is carbon. A carbon track is wrapped around a ceramic core, and two copper leads are attached. A second type of resistor is the metal film resistor, which also has a ceramic core. The track is made from a metal oxide material, which has semiconductive properties similar to carbon. WebbJenny bought a resistor made up of unknown material with color bands (red-green-black- brown-silver) to be used in her school project. She used a multimeter to measure the resistance of the resistor and she found out that the resulting value is exactly the upper limit of the value of the resistance.

The charge that moves past a point on a resistor in a time is given by 𝑄 = 𝑒 × 𝑁, where 𝑒 is the charge of an electron and 𝑁 is the number of electrons that move past the point. The value of 𝑁 depends on the density of free electrons in a substance, 𝑛, and the volume ... WebbThis sounds like a resistor, and indeed it is possible to make resistors from semiconductor material.

WebbA thermistor is a semiconductor made of ceramic materials and it reacts like a resistor which is sensitive to temperature. Usually, bioapplication thermistors have a high negative temperature coefficient, which means that their resistance increases as temperature decreases, and vice versa.
