: : can any one of you Experts give me a circuit digram for constuction of a CELLULAR --MOBILE PHONE charger, I do need it in my project?
Ya Hero,A phone charger is just a small DC power supply.
There is no circuit, just use a DVM to find the positive and negative terminals and connect them to the appropriate connections on your project.
Ya hero,I don't understand the question and you don't seem to understand what I've said.
A phone charger is just a mains adaptor, it converts 230/120VAC to a lower voltage like 5VDC. All you need to know is which pins on the connector are + and -.
There is no circuit, just connect the + to the +V and the - to the 0V on the schematic and it'll work.
