Electrical networks, comprising interconnected resistor elements, form a fundamental framework for analysing circuit behaviour and transport phenomena. The study of resistance theory has evolved from ...
In most operational amplifier (op amp) circuits, the resistor tolerance and resistor temperature coefficient determine the gain accuracy and gain temperature drift (Figure 1 shows a typical circuit).
So, what is a resistor? A resistor is a material that resists, limits or impedes the flow of electrical current. Resistive materials include carbon and various metallic alloys such as nichrome.
