Why is choke coil needed in the use of fluorescent tubes with ac mains?

Advertisements

Solution

A choke coil is an electrical appliance used for controlling current in an a.c. circuit. Therefore, if we use a resistance R for the same purpose, a lot of energy would be wasted in the form of heat etc

  Is there an error in this question or solution?
