What is a ballast?What the ballast is doing
The ballast works by self-induction (self induction electromotive force) to improve on both ends of the tube voltage to make the mercury vapor inside the tube (mercury) ionization electron on the inner wall of the tube On the inner wall of the tube fluorescent material
The ballast is not the initiator and the ballast and the starter are the main components of the fluorescent lamp
High 2 physics has, be used to limit the current too big, can make the lamp tube has stable current in short time! There are two types: inductance and high frequency. The inductance is too large and bulky, so it is generally used in high frequency
