Why does Benjamin Franklin decide to use silk instead of paper in making the kite for his experiment?
Experimental Setup Benjamin Franklin made a kite from a silk handkerchief and two light strips of cedar. He used silk because a paper kite would have been destroyed in the rain. At the top of the cedar arms, a foot long thin iron wire was attached to attract static electricity.
Who was the first person to get struck by lightning?
Roy Sullivan was born on Wednesday, Feb. 7, 1912, in Greene County, Virginia. Sullivan was a United States park ranger in Shenandoah National Park. Between 1942 and 1977, he was struck by lightning on seven occasions.
Did Benjamin Franklin actually fly a kite in a thunderstorm?
On June 10, 1752, Benjamin Franklin flies a kite during a thunderstorm and collects ambient electrical charge in a Leyden jar, enabling him to demonstrate the connection between lightning and electricity. He also invented the lightning rod, used to protect buildings and ships.
Can you fly a kite in a thunderstorm?
Never fly a kite with metal parts or lines that will attract electricity. Never fly a kite in the rain because the kite’s string can carry electricity. Do not fly a kite if there is a risk of thunderstorms or lighting. Never fly a kite near the edge of a steep hill or slope.
Did Benjamin Franklin actually fly a kite with a key?
Franklin stood outside under a shelter during a thunderstorm and held on to a silk kite with a key tied to it. When lightning struck, electricity traveled to the key and the charge was collected in a Leyden jar.
Who has the greatest contribution to electronics?
1. Ben Franklin, Michael Faraday, and Thomas Edison made important contributions to our understanding of and harnessing of electricity.

What is the history of electronics?
Electronics’ actual history began with the invention of vacuum diode by J.A. Fleming, in 1897; and, after that, a vacuum triode was implemented by Lee De Forest to amplify electrical signals. This led to the introduction of tetrode and pentode tubes that dominated the world until World War II.
What were the first electronics?
The first electronic device ever invented is the relay, a remote switch controlled by electricity that was invented in 1835 by Joseph Henry, an American scientist, although it is also claimed that the English inventor Edward Davy “certainly invented the electric relay” in his electric telegraph.
