This means that the resistance remains constant as the current changes. \n- The resistance of components such as lamps, diodes, thermistors and LDRs is not constant; it changes with the current through the component. \n- The resistance of a filament lamp increases as the temperature of the filament increases. \n- The current through a diode flows in one direction only.
