The weekly report provides details of a student's progress on designing a power supply circuit for their engineering project group. It describes the student creating a power supply circuit that produces 12V and 5V outputs, and includes calculations of current draw for components in a microwave and refrigerator. Figures of the printed circuit board and circuit diagram for the power supply are also included.

Weekly Progress
This week I made a Power Supply.When I found was that the power supply circuit of
the required 12 V and 5V.I was told to use replace 5V .I need to calculate
the total flow used in microwave circuit by the use of the refrigererator is 153.25 mA
and 83.5 mA with a current total value of the capacitor used in the circuit are as
follows.Calculated the value of the capacitor value used in the microwave is
1000ufand used in the refrigerator for the same 1000uf.

Engineering Analysis
Strong Point
I made a circuit to the PCB and may be a problem when the circuit may
caseequipment damage, so be careful as well.
Week Point
I have learned to write more programs. Can be applied to a circuit party.
Next Week Job
The proposed project must be made.
