Resistors

A resistor is an electronic component that limits the flow of electrical current. It's characterized by its resistance, measured in ohms, and dissipates energy in the form of heat. Resistor values are determined by their color-coded bands or marked values. They're used in circuits to control current, voltage, and signal levels, enabling precise adjustments and protection against excessive currents. Resistor types include fixed (carbon film, metal film) and variable (potentiometers, rheostats), offering a range of resistances for diverse applications in electronics, such as voltage division, signal filtering, and current limiting.
