Here is Solar power supply circuit delivers either 4.8 or 7.2 V regulated at 15 mA with a 3-V input from a bank of photocells. Rl should be 453 kQ for a 7.2-V output and 274 РЁ for a 4.8-Vdc output. Regulator efficiency is around 70%. This should be considered when selecting suitable solar cells. Build a Solar power supply Circuit Diagram

Power Supply on a computer is an energy source that drives the computer you. With power supply, hardware on the computer is given "power" to can work in accordance with their respective functions Power Supply on a computer to work as a flow modifier (Adapter) from AC current into DC.  Power supply is working on 2 pieces of 5-volt DC voltage and 12 Volt. In a power supply, voltage 12 volt is usually characterized with a yellow cable, while the voltage is 5 Volt is marked with cable red. Tips to maintain power supply in order to remain durable 1. Make sure you buy the power supply to suit your computer needs. Buy power supply that is guaranteed quality. 2. Make sure when you install a power supply on your computer already in the correct position. Make a tightening of the socket-outlet power supply to the motherboard, hard drive, CDRom, etc.. If you do the installation is not correct it will be fatal and can be a fire or a short-circuit will occur on...
