Inventions that changed our way of life

Electricity Today we can’t imagine our life without electricity. Everything we use is operated with electricity.

Electricity's extraordinary versatility as a means of providing energy means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation. Electrical power is the backbone of modern industrial society.

The word electricity is from the New Latin ēlectricus, "amber-like", coined in the year 1600 from the Greek ήλεκτρον (electron) meaning amber, because electrical effects were produced classically by rubbing amber.

Benjamin Franklin conducted extensive research on electricity in the 18th century, as documented by Joseph Priestley (1767) History and Present Status of Electricity, with whom Franklin carried on extended correspondence.

LIGHT BULB One of the important invention that brightens millions of houses and buildings.

The bulb itself works by transmitting electricity through a wire with high resistance known as a filament. The waste energy created by the resistance is expelled as heat and light.

Thomas Alva Edison was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long- lasting, practical electric light bulb.

The coastal steamship Columbia became the first application for the light bulb in 1880. It sank after colliding with a schooner off California in 1907.
