This paper is an overview of the sources and nature of various transient over voltages and the problems that may result in a low voltage ac distribution system. Voltage transients may be repeatable transients or random impulses and they have got remarkable effects on semiconductors, electrochemical contacts, insulation etc. Switching parallel loads on the same branch of distribution system as well as lighting are responsible for these transient overvoltages. Low voltage ac mains system should be protected from these transient overvoltages. For ....etc

REGULATED POWER SUPPLY
1.1 Types of Power Supply

There are many types of power supply. Most are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronic circuits and other devices. A power supply can by broken down into a series of blocks, each of which performs a particular function.
For example a 5V regulated supply:

Each of the blocks is described in more detail:

bubble power over electical applications

Abstract
In sonofusion a piezoelectric crystal attached to liquid filled Pyrex flask send pressure waves through the fluid, exciting the motion of tiny gas bubbles. The bubbles periodically grow and collapse, producing visible flashes of light.

The researchers studying these light emitting bubbles speculated that their interiors might reach such high temperature and pressure they could trigger fusion reaction. Tiny bubbles imploded by sound waves can make hydrogen nuclei fuse- and may one day become a ....etc
