please solve it and thank you
converting 220v Ac to 12V DC :
1. Design specification
2. Specification of each of the component used in theproject
3. Transformers, Step-down transformer, transformer ac input/ acoutput specifications
4. Rectifier (forward and reverse biasing diode, half waverectifier, full wave recifier)
5. Peak Inverse Voltage, Calculation of Peak inverse voltage
6. Filter capacitor
7. Unregulated Power Supply
8. Voltage regulation using an IC 7812
9. Percent regulation with Zener diode and 7812
10. Comparison of design specification with actual result.
