that limit current flow and divide voltages in electronic circuits. Governed by Ohm\u2019s Law (V=IR), their resistance (R) determines how they control energy as heat (P=I\u00b2R). From fixed resistors to variable types like potentiometers, they enable precise circuit tuning, signal attenuation, and protection against overcurrent. Key applications include voltage dividers, LED current regulation, sensor interfacing, and analog signal processing.
