Cathode Lamp
Cathode Lamp
why manufacturers do not provide cathode resistance of fluorescent lamps?
If you mean why don't lamp manufacturers build extra resistance into the lamp, it is because the lamp is disposable and the external ballast outlasts the lamps. Building it in would unnecessarily raise the cost of the lamps.
