KNOW HOW ATUBE LIGHT WORKS,MADE IT YOURSELF



How are you readers? Hope you all are well, don’t forget to give your valuable comments to improve my site, let’s start-
ALL of you have seen fluorescent lamp, simply to say tube light do you know how it really works?

Working theory-the glass tube is filled with mercury vapour in a very low pressure, when the filament emits electrons, it hits the mercury atom, as a result of the collision, uv rays are emitted, and hits the phosphor coating of inside of the glass tube, and reflects uv and makes human eye visible white bright light,

WITHOUT TRANSFORMER 220 VOLT AC SUPPLY TO 12 VOLT DC CONVERTER




THANKS READERS FOR COMING AGAIN ON www.abhieeeprojects.blogspot.com

TODAY’S PROJECT

WITHOUT TRANSFORMER 220 VOLT AC SUPPLY TO 12 VOLT DC CONVERTER

Introduction-it always happens that we make a project, but it needs power supply of 6 or 12 volt dc,
Buying transformers for every project is really expensive, so what can we do, here i am going to give you the solution,
You can make the transformation with a few cheap electronics components,
Components required=general diode, capacitor, resistor, zener diode.
Circuit diagram= see the picture given,
we all know that voltage drops across the load. at the starting of the circuit we use a parallel combination of resistor and capacitor to limit the current. the current is very less in the circuit but voltage is almost same as supply  voltage, when we connect load at the output of  the circuit,voltage drops significantly, so we get 12 volt or less according to load. this circuit is suitable only for light load purpose for greater load ,transformer is better option. you can get this type of circuit from china rechargable torch light.
 
If you have any question, you can ask me, i am waiting for your response,
