Stock. Electric clocks! Rare topic! Electric clocks are clocks moved by an electric current. The electric clock was invented in the first half of the 19th century. In 1820, the Frenchman André-Marie Ampère invented the electromagnet and proposed bases for studying electromagnetics (the magnetic effects of electric current). This property is used in electric motors, loudspeakers, recording devices such as video recorders, tape recorders, etc. In 1840, the Scottish watchmaker Alexander Bain made the first electric clock. The energy is supplied by a cell which supplies an electromagnet which causes a pendulum to oscillate. He also imagines that a central clock could send electrical signals to synchronize many other clocks. This idea was put into application by Louis Clément François Breguet in 1856 who installed in Lyon a system capable of operating 76 dials housed in the lanterns of street lighting connected to each other by a network of electric wires. The mother clock, powered by an electric battery, is connected to a regulator which sends a current inverted at each minute into the conductor to ensure that all the dials are displayed the same time.

By 1900, electricity began to spread (power grids). Home use of electric clocks becomes possible. The first practical electric clocks were made in 1918 by Henry Ellis Warren(en), an American electrician. They operate with a synchronous motor slaved to the stabilized frequency of the AC power grid. It succeeded in convincing the electricians to offer the distribution of time as a service after the low (but constant) consumption of the clocks became measurable. The low investment required to ensure high stability is more than offset by the additional consumption generated by the multiplication of the clocks. In the 1950s, technical progress made it possible to develop electric watches. The development of quartz watches in the 1970s made this technique obsolete. Read more at

A stock certificate is issued by businesses, usually companies. A stock is part of the permanent finance of a business. Normally, they are never repaid, and the investor can recover his/her money only by selling to another investor. Most stocks, or also called shares, earn dividends, at the business's discretion, depending on how well it has traded. A stockholder or shareholder is a part-owner of the business that issued the stock certificates.
