The diode was placed in a reverse position.It was a Circuit wizard failure. | Repeated the procedure.Placed the diode correctly. | Division of Labor: Gilbert – casing, circuit diagram, soldering Ellaine – Drilling of holes Audrey – Soldering components Joanne – Documentation, Ironing of tracks Receipt: (1) PCB 40 (1) Lead 12 (2m) wire 20 (1) Alligator Clip 10 (1) Ferric Chloride 35 (1m) wire 18 (1) plug 10 (5) resistor 5 (1) pc capacitor 3 (4) diode 2A 12 (2) shrinking tube 45 Photocopy 30 (4) Diode 20 (4) Capacitor (2200,10,1,0.1) 30 ------------------------------------------------- Transformer 450 ------------------------------------------------- Case 150 Total 890 Abstract: A power supply is a device that supplies electric power to an electrical load. The term is applied to the devices that convert one form of electrical energy to another. A regulated power supply is the one that controls the output voltage to dc value. A regulated power supply converts an unregulated ac to dc. Today, almost any electronic devices needs a dc supply for its smooth operation and they need to be operated in certain power supply limits. Conclusion: Based on the components of the project, the proponents conclude...
