Resistorer
Resistorer, called resistors in English, are passive electrical components that provide a defined resistance in circuits. They limit current, divide voltages, bias active devices, and shape signals, often dissipating energy as heat.
Fixed resistors use materials such as carbon film, metal film, metal oxide, and wirewound constructions. Variable
Key specifications are resistance value, tolerance (commonly ±1% or ±5%), power rating, and temperature coefficient. Values
Construction affects performance: carbon composition, carbon film, metal film, metal oxide, and wirewound. SMD resistors use
Applications span power supplies, audio, computing, and consumer electronics. They are generally reliable, but drift with
Resistors are described by Ohm's law and are fundamental in both analog and digital circuits. The term
