Capacitance vs. Resistance
Unlike capacitors and inductors, resistors do not exhibit frequency-dependent characteristics. They provide a constant resistance value regardless of the frequency of the applied signal. This property makes resistors suitable for applications where a consistent resistance is required, such as voltage dividers and current sensing circuits.
