    The purpose of choke in tube light is ?

    • A.

      To decrease the current

    • B.

      To increase the current

    • C.

      To decrease the voltage momentarily

    • D.

      To increase the voltage momentarily

    Correct Answer
    D. To increase the voltage momentarily
    Explanation
    The purpose of a choke in a tube light is to increase the voltage momentarily. A choke is an inductor that stores energy in its magnetic field when the current passes through it. When the current is interrupted, the choke releases the stored energy, causing a momentary increase in voltage. This voltage spike helps to initiate and maintain the ionization process in the tube light, ensuring that it starts and operates efficiently.
