How was electricity discovered?
Micheal Faraday discovered the relationship between magnetic fields and electricity traveling in a wire. This led to the brilliant work of Tesla. He is the father of modern electricity. He invented the shaded pole electric motor. Still the heart of most systems today at the house or factory. Others shaped the finer details.
In 1752, Franklin is said to have performed the famous experiment of flying a kite during a thunderstorm, to which led to the discovery that lightning and electricity were somehow related. Modern scientists know this to be something of a tall tale, since being hit by lightning would have been fatal. It's likely that Franklin was actually insulated, away from the path of lightning.
Phenomenon associated with stationary or moving electric charges.
The word comes from the Greek elektron("amber"); the Greeks discovered that amber rubbed with fur attracted light objects such as feathers. Such effects due to stationary charges, or static electricity, were the first electrical phenomena to be studied. Not until the early 19th century were static electricity and electric current shown to be aspects of the same phenomenon. The discovery of the electron, which carries a charge designated as negative, showed that the various manifestations of electricity are the result of the accumulation or motion of numbers of electrons. The invention of the incandescent lightbulb (1879) and the construction of the first central D.C. power station (1881) by Thomas Alva Edison led to the rapid introduction of electric power into factories and homes. D,C, proved not to be the way to transmit power over any distance. A.C. from Teslas' inventions supplanted Edisons' equipment rapidly.
Michael Faraday, Luigi Galvani, Alessandro Volta, Andre-Marie Ampere, and Greg Ohm did work that provided the basis for modern electrical engineering.
Italian physician Girolamo Cardano returned to the subject of electricity in De Subtilitate (1550) distinguishing, perhaps for the first time, between electrical and magnetic forces. In 1600, the English scientist William Gilbert coined the modern Latin word 'electricus' from 'elektron', the Greek word for 'amber' which soon gave rise to the English word - electricity.
Otto von Guericke invented an early electrostatic generator in 1660. Other European pioneers were Robert Boyle, who in 1675 stated that electric attraction and repulsion can act across a vacuum. Stephen Grey, who in 1729 classified materials as conductors and insulators, and C. F Du Fay, who first identified the tow types of electricity that would later be called positive and negative.

Was Benjamin Franklin actually a fictional person who was fabricated by the Learned Elders of Zion?
While the evidence for the historical presence of Benjamin Franklin is considered a settled matter (meeting the generally accepted standard of five independent proofs), the authorship of some of the literary works attributed to him has been questioned. One increasingly popular theory is that while Benjamin Franklin was a real person, his body of work and literary persona is attributable to the efforts of the Learned Elders of Zion. The evidence for this is far from conclusive, but too strong to be casually dismissed without further investigation.
What musical instrument did Benjamin Franklin invent?
The harmonica
-----
Benjamin Franklin invented an instrument called the glass harmonica, which is rarely seen today and is not related to the harmonica we commonly see and hear played.
Franklin's harmonica was based on earlier designs consisting of sets of glasses, partly filled with water, that were rubbed with a wet finger. It consisted of a series of crystal glass hemispheres, mounted on a shaft that went through their centers. When the shaft was turned, the hemispheres rotated, and a wet finger applied to make them sound. Unlike the glasses, which were tuned by filling with varying amounts of water, the harmonica hemispheres were tuned at the time they were made, according to their size.
There is a link below to the section on Franklin's instrument in an article on the glass harmonica.
