POWER SUPPLY UNIT.

A power supply unit is a process by which the voltage output of a device is being determined by the regulation made by its manufacturer.
Types:
⦁ Linear power supply unit.
⦁ Switching mode power supply unit.
We shall be discussing the linear power supply unit. we are going to be needing the following:
1. Voltage regulator.
2. Bridge rectifier.
3. Capacitor.
4. Diodes
5. Fuse.
6. Switch.
7. Resistor.
8. Transformer.
Arragement:
Supply from the AC goes to the fuse then a switch is attached followed by a transformer, then to bridge rectifier, then diode, voltage regulator and a resistor.
