Which Components to use?
I want to make a circuit that is powered by 220v ac. It consists of a cooling fan that requires 12v, 0.7a, a PCB with 10 LEDs in parallel that requires 0.25a, 3.5v and a single led that requires 3.5v,0.025a. I know how to calculate resistor values but it would be better if you give the values. I want to know which diodes should I use to make the rectifier and should I use a capacitor? In short, I want to know how to set up this circuit, what components to use and their value and power ratings.
