Rectifier Problems!? Answered
I got a problem in my rectifier it is not able to charge my cell phone but it's giving out 4.5 volts of current i measured it with my multimeter and my cell phone also needs and input voltage of 4.5 volts. I think my rectifier ( it's circuit is in the given in the image! ) is not good and need to be modified so i can charge my cell phone. Can anybody give me the circuit with a output voltage of 4.5 volts and it's so rectified that it can charge my cell phone .
