12 volt battery charger

12-volt battery charger:

This is the 12-volt battery charger. this circuit is a simple circuit diagram. but this circuit is dangerous. we can use this circuit without touching it. this circuit makes 12 voltages and 500mA. but this circuit can electrically shock. we can change the small battery. like 4/5 amperes 12 voltage battery. 

Here used 105j 400 volt pf. one 1M resistor. one bridge diode. two 25-volt 1000uf capacitors. one 12-volt ziner diode. one coil for making pure dc.
