Correct option is D
· In a tube light circuit, the choke (or inductor) plays a crucial role in the starting process. When the tube light is turned on, the choke generates a high voltage spike due to its inductive properties.
· This high voltage is necessary to ionize the gas inside the tube, creating a conductive path between the electrodes. Once the tube light starts, the choke also helps in stabilizing the current by limiting the current flow through the circuit.
· While it also limits the current after starting, its primary role is to induce the initial high voltage required to start the tube light.
