What's inside a magnetic ballast which is used to start tube light


Magnetic Ballast
           An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in alternating current fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the negative differential resistance artifact in the tube's voltage-current characteristic.

     In below i give you a link where you can get information about types of magnetic ballast.


Wait for my next post.If you any query you can command below.
