Magnetism and an electricity. Gemfri the Davy

you are: Magnetism and an electricity

From two thousand elements Volta the English physicist and chemist Gemfri of the Davy (1778-1829) has created a coal arch which became the first source of electric light. After a while researchers have started to build more perfect elements which are used and until now. They differ from voltova a column as concerning a current strength, duration of action, and considerable convenience of use.

Alessandro Volta investigated also occurrence of electric charges at contact of two metals. This experiment used in due time a great popularity, it showed at royal and imperial court yard. Except the thermoelectric battery, Volta has constructed also elektrofor, electrometer, the condenser and audiometer.

Achievements Volta have caused general enthusiasm. Physicists repeated and developed its experiences. Great French physicist Arago has told, for example, that, in its opinion, voltov the column is ' the most wonderful device what has ever been created by human mind '.
