The purpose of choke in a fluorescent lamp is : A. To increase the current flow B. To decrease the current flow C. To decrease the resistance D. Ro decrease the voltage momentarily

The correct answer is: B. To decrease the current flow.

A choke is an inductor, which is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. When the current is switched off, the magnetic field collapses, inducing an electric current in the opposite direction. This is called inductance.

In a

fluorescent lamp, the choke is used to limit the current flow through the lamp’s ionized gas. This is necessary to prevent the lamp from overheating and damaging itself. The choke also helps to stabilize the voltage across the lamp, which ensures that the lamp produces a consistent light output.

Option A is incorrect because the choke actually decreases the current flow. Option C is incorrect because the choke does not decrease the resistance. Option D is incorrect because the choke does not decrease the voltage momentarily.
