In this lecture I will present a survey of the developement of the ideas regarding electricity, starting from the findings of Stephen Gray, who found that electrical force is affective away from the place where it was exerted.
During this period of developement, twoÂ new sources of electric force were discovered, one exerted by a chemical reaction, and the other as a combination of magnetic force and movement. These descoveries resulted with many technological application of electricity.
The developements that occured during these years are used for electricity education at the elementary school and intermidiate school, as will be demonstrated through the lecture.
