Components use:
- capacitor X 2
- rectifier diode X 2
- l.e.d
- Z diode
- voltage regulator
- 3 X resistor @ 1800ohms 2700ohms 8200ohms
12v going through diode then to z.d then to the cap (store voltage) and then input of the voltage reg with the feed back resistor for protection its regulates the voltage down to 5v. we also have a gound out put, 12v out put, l.e.d to show that it is working. at 1st it didnt work as it was ment to work because D12 was shorting
we worked out the resistor by using ohms law R = V/I
volt drops
- diode13 0.6v
- cap12.2v
- volt reg 5v
- R1 3.9v
- led 1.78
- R3 3.3v
- R2 1.14v
again your explanation shows you do not understand the circuit, your volt drop should be explained using the principles and concepts we have discussed during this part of the course, also a reflection is need.
