The purpose of choke in a fluorescent lamp is – (1) to increase the current flow (2) to decrease the current flow (3) to decrease the resistance (4) to decrease the voltage momentarily
(2) to decrease the current flow Explanation: The choke primarily serves to limit current flow to the correct level for the tube. It also can be used during startup to provide an inductive 'kick' forming a momentary highervoltage pulse to start the lamp.
