-
was supposed to be the first to use a lodestone as a compass
-
Discovered taht amber rubbed with animal fur attracted light objects (he was not the first to do this but he was the first to record his findings)
-
Invented a lightweight tool called a versorium that looked like a compass but didn't use a magnetized needle
-
Showed that electricity could be transmitted by using a wet string to conduct electricity several feet
-
Removed air from a glass globe and made the globe rotate while rubbing it with a wool cloth
-
Discovered conductivity
-
Came to conclusion that everything and everybody contained electricity
-
Discovered that a dead forg's muscles twithced when it was placed near an electrical mavhine
-
Best known for inventing the voltaic pile (now known as the battery) the volt was named after him
-
Invented a storage jar called a Leyden jar, that showed that electricty could be stored for future use
-
Contributed to the measurement of electric current and who experimented with electromagnetism
-
contributed to the creation of the telegraph
-
Created a set of units to measure the amount of magnetic induction. the unit is called a gauss
-
Discovered the relationship among voltage, current and resistance in a circut using direct current (Ohm's Law)
-
Invented the incandescent light bulb
-
Invented the induction motor, and set the standard for the frequence of the transmission current
-
his experiments helped invent the motor, generators, transformers, telegraphs, and the telephone. he also invented words we use today, including, electrode anode, cathode, and ion.

As a storm was about to break, Franklin flew a kite with a stiff wire pointing up that was attached to the top of the kite. he attached a metal key to the other end of the string and let it hang close to a Leyden jar. rain poistend the string, which benan to conduct electricity. sparks jumped from the key to the jar until the jar could not handle any more charges
